This is my second purchase of this alarm clock the 1st one I bought was in 2015. Well it quit working in 2021. The clock worked but the alarm function and blue tooth quit. So I was hesitant to purchase this again. Back in 2015 there were not allot of alarm clocks that would play off a sd micro card. Now there seems to many that copied off of this one with more buttons and not sure if the others would randomly play a song off the sd card like this clock does. So now its a [Upgraded Version]. Here is what I found different in the [Upgraded Version] which they do not explain. #1 it used to make a beep sound when the alarm button is pressed on. No big deal I did like the beep it reaffirmed it was set. #2 24 hour clock mode no longer has 4 digits unless needed for the time display. #3 way better more accurate temperature gauge display. Other then that it now comes in white. But main reason I like the clock is random song selection to wake you up. Makes it not feel like Bill Murray's movie Ground Hog Day.Easy to set up.Adjustable brightness.usb A charging a plus.We have been using two of these Hometime alarm clocks for several years. Overall, it is functional as a clock, alarm, and Bluetooth speaker. The device is easy to setup and pair with an iPhone. Adjustments (12/24 hr time, C/F temp, and brightness) are very easy and straightforward. Music streaming via Bluetooth is poor quality but about what I expected for such a cheap alarm clock speaker.The real negatives are (1) slow USB device charging speed and (2) built-in thermometer accuracy. It is possible that the alarm clock has been updated since we purchased them several years ago. However, the USB charging speed via the two devices we own are quite slow. Adequate for an older iPhone or Apple Watch...but not fast enough to readily charge a recent generation iPhone or iPad.The second issue is the temperature reading for the built-in thermometer. It is simply not at all accurate. We have 2 Hometime units very close to each other (1 on either side of a bed) and they often display vastly different temperatures for no apparent reason (sometimes 5-10 degree F different).Overall, the Hometime device is just average. Understandably, it designed for limited tasks (clock, alarm, Bluetooth speaker, thermometer, and USB charging), but it fails at 2 of the 5. For the price, I expect more -- or at least all of the claimed features to work.Best alarm clock I've seen. The dimmer is great... 4 settings including off. Easily change the time or set the alarm with the rotary dial in top. Don't try to switch from minutes to hours etc. Just dial up or down to the time you want.Charging up the phone while I'm writing the review. While listening to music with the Bluetooth. Great price for such a hardworking clock that doesn't hog up precious room on my bedside table. Tossing my old clock and bringing in a floral arrangement now that I have room.UPDATEwhen I plug my phone in to charge, it zeros out the clock and I have to reprogram it. This has happened so often the temperature setting is stuck on Celsius because the interior button (needs a paperclip to change) has broken. I ordered two and the other one is still in the box. I was saving it to put into a newly remodeled guest room and have to hope it doesn't do the same thing for them. This is no longer a 5 star item.The best alarm clock I've EVER had. Super easy to set which was one of my requirements in a new alarm clock. The three brightness setting are perfect. I use the lowest at night and in the morning change it to medium. I like the convenience of two usb ports. The microsd slot is fantastic too. I can wake up to my favorite piano music. The default tones were pretty good also. The gradual volume increase on the alarm is also infinitely superior to my old alarm clocks. My only wish is that it had the USB ports on the side. It would look a little better than having the wires hang out the front.After multiple late days at work thanks to my unreliable phone alarm, I decided that I needed to purchase an alarm clock. I researched multiple different options and settled on this one. I'm so glad I did! It's simple enough to figure out and I love the way it looks. It's reasonably stylish and it's pretty small, which is great for my nightstand. You can dim or turn off the display light, the Bluetooth speaker works pretty well, and the alarm is reliable. It's a pretty soothing sound but it gets me up every time! I am so grateful for my amazing new alarm clock!As described.Love how small yet streamlined and efficient this clock radio is! Love the dimmable readout and other welcomed features.What a great little clock. I can play my music through it and charge my phone at the same time.The time display turns off keeping the bedroom dark or I can set it to one of three different light levels. Would definitely recommend.Small and smart, easy to set up. Once set up its press one button to reset alarm each day.The digital display can be really bright, that's what I want. The 2 USB chargers can charge up my device quite fast.I love this gadget!! Display really clear and can be turned down to suit. Sound quality good.First class product charges me devices and gets me up for work what more do you want
