I'm happy
So far, so good. I wanted an inexpensive setup for my golf cart and purchased this set. Connects easily to my phone and puts out a lot of volume. My only issue is the mounting sleeve. It's not much thicker than aluminum foil. Since I was installing it in a golf cart that didn't have an existing opening for a stereo, there was a lot of test fittings which required mounting it and then removing. The sleeve would distort and getting it to snap back into the receiver after each removal was getting increasingly difficult. Probably wouldn't be an issue in a vehicle designed to accommodate a stereo. Just out of curiosity I compared the sleeve of this stereo to an old Kenwood I had removed from my Harley. The Kenwood sleeve was so much sturdier. I realize this is a cheap stereo and didn't expect mind blowing performance like an Alpine, Sony, Pioneer, etc. so I'm not claiming it's comparable. It's a $50 set that gives you a good enough experience.

Great radio
I've been using this radio for a while now and so far I love it. The sounds not bad especially after you mess with the eq settings. You can change the brightness relatively easily as well. The speakers it comes with aren't too bad and I'll probably keep them as a backup in case my current ones go out. I mostly use Bluetooth and so far no issues with the display going out or sounds dropping. Great radio. Additional information 5/15/2018: My screen went blank once and I contacted customer support. They were quick and informative also giving me a PDF describing exactly what they were telling me so I could see visually. If you have screen issues all you have to do is hit the tiny reset button with a thin object. That fixed mine right up.

Decent quality
Pretty bad sound overall. I swapped it back out with a sony that is only 50 watts and the sound quality was night and day. But the Sony was 120 dollars. This thing is only 37 bucks. Works for a simple radio in an old truck but not amazng. Speakers were a bit crackly at times. But it has ok settings and a decent display. Know what your doing before you hook it up.

Did not work for me, it lost dysplay same day I installed it.
I bought this unit and shelf it for a few months. Last weekend I installed in my toyota 4 runner. I powered up to test, all working fine. I shut off to put all trim and stereo in housing, all fit well. When I powered up and all in place , half the display is gone, i don't know what is playing or what station. I have to remove and purchase new stereo. I'm disapointed because it was a lot of work to install all trim back together. No warranty I guess.

Affordable plug and play performance
Easy to install, even though I had to splice wires…I’m electronically savvy so it was not an issue. The new speakers sound better than my old stock Chevy Silverado 1500 ones. Good quality at a great price for the package

This particular package was ‘missing’ or just untracked for a few days. However, it was delivered 1 day late which i think is pretty reasonable. Soo no complaints from me, because… well stuff happens. Also, grandson loves his gift, 👍👍

This is a great little system with good sound. The 2 speaker with deck sounds really good in my side by side. Did a little custom work and looks great! Was easy to hook up Bluetooth.

Es un buen equipo que cumple su función. Se instala sin problema y funciona con bueno sonido. La iluminación azul del panel de botones es mucho mas brillante que el display de estaciones y no es fácil mirarlo cuando es de día. La función de "manos libres" cuando recibe uno una llamada es algo defectuosa, el e te llama no escucha muy bien la voz de uno.
