Continuous Optimization and Upgrades

The SMATRUL doorbell continues to improve and upgrade, bringing you a brand new diamond-cut design. Not only is it more beautiful, it also offers more comprehensive functionality: doorbell + SOS call + colorful night light, a practical three-in-one design that makes life safer and more convenient.

We constantly listen to our customers and continuously improve our products to provide you with a better experience.

--[Lifespan]

The transmitter is tested to 100,000 presses. Powered by a CR2032 battery, it boasts an exceptionally long battery life of 8 years (based on two presses per day, each lasting two seconds).


--[Over 350m Wireless Signal Range]

Continuous optimizations have enabled this wireless doorbell to receive signals from a distance. The strong, penetrating wireless signal provides an ultra-wide range of 350 meters, capable of penetrating steel and wooden doors and walls. Please note that this distance is in the open air.

--[Diamond-Cut Appearance]

Diamond-cut craftsmanship: The unique diamond-faceted appearance creates a stylish and premium look when light and shadow are reflected.

 

Crystal Clear Texture: The diamond-like design dazzles, making it more than just a doorbell; it's also a home decor accessory.

 

Light Mapping for Even More Beauty: The dazzling night light combines with diamond-cut facets to create a warm atmosphere.

 

Simple + Luxury: The white exterior with diamond-cut finishes complements any decor style.

 

--[5 Lighting Modes + SOS Alarm Mode]

 

1. Flowing Color: Different colors connect to form a ring, flowing and changing.

 

2. RGB Flow: Continuously switches between solid colors like red, green, and blue.

 

3. RGB Breathing Light: Shifts between bright and dim in a rhythmic manner, like breathing.

 

4. Constant Color: The colored rings remain constantly lit.

 

5. Constant Night Light: Continuously illuminates in white, serving as a night light.

 

SOS Alarm Mode: Can be paired with an SOS button. When triggered, it emits a sharp alarm sound and flashes a red light.

--[110dB Ultra Loud Volume]

The receiver's maximum volume reaches 110dB, allowing the ringtone to be heard throughout your home, ensuring you never miss a guest.

--[Power Failure Memory]

After a power outage, the doorbell will retain your volume, music, and lighting settings, allowing you to easily restore your preferred settings.

--[Front and Rear Door Distinction]

When a receiver is paired with two or more transmitters, you can set different ringtones. The receiver must select a tune before pairing. The transmitter will then lock the currently selected tune. If your home has two or more front doors, this feature helps you instantly identify which door a guest is entering.

--[High-Quality Copper Pins]

Compared to most doorbells on the market that use iron pins, we opted for copper pins. These pins are more resistant to oxidation and corrosion, resulting in better conductivity.

 

--[62 Music Tracks]

The doorbell features 62 melodies for you to choose from. (Shortcut: Long-press the "Previous Song" button to instantly return to the first track.) The doorbell volume is adjustable to four levels: loud, medium, soft, and silent. Within ten seconds of selecting your preferred tune, press the transmitter to select it.

Disappointing
Format: Hardcover
I had high hopes. But this book seems to be more of a rosy retrospective of one college president years in charge than it is a real useful book about how to help students.

Reminds us of the value of a college education beyond academic facts and skills.
Format: Kindle
At a time when many students and families are questioning the value of a 4-year college education, Porterfield does a great job of describing the intangibles behind an earned degree. Many people are aware that there is more to a college education than academic facts and skills, but this book presents the case comprehensively. It identifies "soft skills" specifically and gives good examples of how they can be taught and learned in the college environment.

Loved it!
Format: Kindle
Mia is a ten-year-old Chinese immigrant. She had immigrated to California from China 2 years earlier with her parents, who were hoping for a better life. Unfortunately, the United States in the 1990s was not exactly welcoming to Chinese immigrants, and many struggled. Mia and her parents were no different. After gaining and losing several jobs and facing homelessness again, Mia's parents take a job managing a motel. Unfortunately, the motel owner - who is Taiwanese, not Chinese, as he is quick to point out - is not only overtly racist, he is also exploitive and seems almost happy to point out to Mia's parents that they could be replaced immediately when they question his actions. But Mia and her parents try to make the best of it. Mia works the front desk when at the motel, quickly learning the ropes and consistently trying to find ways to help the guests and her family. She also becomes friends with the weeklies at the motel - those guests who live at the motel and pay weekly - and they quickly become part of her growing family. At school, though, Mia struggles. She can't tell the other students - most of whom are white - that she lives in a motel. She struggles in English, though she loves writing, and she also has disagreements with her mother who thinks she should focus on math and forget about writing because "she'll never be able to write as well as the white kids" for whom English is their native language. Most of the book is a slice-of-life look at running a hotel and Mia's struggle to integrate with the other students at school. Though it may seem to some that too much goes wrong at the motel in too short a period of time, I can say from experience that this depiction is incredibly realistic. While reading it, I was having flashbacks to my own experience managing a motel and running the front desk. The news Mia and her family get in chapter 55, in particular, hit hard on the feels for me, because my husband and I went through that same situation. We didn't use the same solution that Mia and her family did, and I definitely loved the solution they came up with. Throughout the story were the letters that Mia wrote, each for a different situation. These were an added touch, helping to bring the reader back to the days of the early and mid-90s, before email was ubiquitous and text messaging was still a dream. Her struggle to put word to paper, to make sure she was using the right words and tenses, was an added dimension to the story that I didn't expect but definitely appreciated. The author's note at the end, where she discussed her own experiences was also incredibly moving, and I loved learning that much of the book's scenarios were pulled from her own experiences, while also wanting to give a hug to the child that had to experience that struggle. I had the opportunity to listen to the audiobook, narrated by Sunny Lu, and I highly recommend it. Lu did a wonderful job with the narration, injecting just the right amount of emotion and tension into the performance. I had to force myself to stop listening so I could go to bed; had I not, I would have listened right through to the end and not getting any sleep. While I would have enjoyed the story, work the next day would not have been fun. Lol. So, long review short, I definitely recommend this book. For younger readers, I would recommend a parent read with them, as there are some tough situations that they may need/want to talk about. But overall, this is a story of hope for an immigrant family who is struggling to make a better life for themselves.

My favorite middle grade book of 2018 so far
Format: Hardcover, Format: Hardcover
I'll never look at a motel with the same eyes again. Author Kelly Yang brings us Mia Tang, a younger version of herself, who helped her parents manage a motel in southern California in the early 1990s. Mia and her parents arrive from China with two hundred dollars, unwavering optimism, and the belief that if they work hard enough, they will achieve the American dream:  a big house, a dog, and an endless supply of juicy hamburgers. After two years of backbreaking jobs and sketchy living conditions, Mia's parents rush to sign a contract to manage the Calista Motel located five miles from Disneyland. Mr. Yao, the notoriously cheap and unscrupulous motel owner, informs the Tangs that the contract allows him to make any changes and if they don't like the terms, "Just say the word. There are ten thousand immigrants who would take your job in two seconds" (p. 27). Mia quickly makes friends with the "weeklies" and assigns herself front desk duty because her parents must clean every room themselves and be available 24/7  to check in guests. Mia's moxie and sense of justice emerge as she takes on adult responsibilities with a sense of pride and unbridled enthusiasm. She makes plenty of mistakes which makes us empathize with her struggles and root for her as she tackles the english language, bullies, crime, and embarrassment about her thrift store clothes. (Keep your eyes open for the tale of the designer jeans.) Chapters are vignettes that are strung along with seamless transitions to make reading a pure pleasure. The author captures Mia's voice so authentically that the reader is instantly drawn into the story. Mia's uses the power of the written word to advocate for herself and others. Kids will fall in love with Mia and cheer her fierce determination as she navigates her way through poverty and injustice, bringing her family, the weeklies, and everyone else who want to be part of the American dream with her.
