5 stars for sure. Unbelievable for $23. Seller very responsive too with my questions pre-purchase. I have this outside near a small pond with ducks and our chicken coop. I installed in inside a plastic ammo box on top of the 4x4 post that holds the outlet. I use a dusk to dawn timer and have a usb drive inserted into it (connected to 2 outdoor speakers). The unit defaults to playing the usb drive when powered on and repeats the tracks in order until it is powered off. I have sounds and music intended to scare away coyotes and bobcats. So far it's perfect. I can also connect with Bluetooth and the unit is a powerful little jukebox. FM stinks and Bluetooth range is not great but for $23 plus some Rockville $55 speakers and a $6 ammo box it's impressive as heck!

This little sucker jams. I love itAnd it's hooked to indoor/outdoor Rockville speakers and let me tell you the pair together rocks. It's on my front porch and yes the neighbors can hear it rock lol.

It works OK. As other reviewers have mentioned, the power on volume quirk is annoying, but not a deal breaker.

great sound and reliable, it works 24 hours by me. and its good

I purchased this to add bluetooth to an older stereo. I went this route because sometimes bluetooth volume is low and this option gives the opportunity to adjust for that as well as make minor adjustments on treble and base. It''s been a little difficult to get the volume settings right to control distortion. If any one of the volume settings is too high, there will be sound distortion. One of the problems is that there are two volume adjustments, the knob on the front of the device and the one with the remote. There should only be one but that's not the way this works. So between the volume on my phone, the two volume settings on this device and the volume on the old stereo it's easy to get one too high somewhere.The larger issue is that by feeding the older stereo from this device, it introduced a hum. I tried several ways of connecting the two and finally found a solution when I powered the unit with a decent quality DC power supply. There are two power inputs and an AC power cord is included. However, there is a power input for 12VCD. Once I powered it with DC the hum was eliminated. This hum, also added to the difficulty of getting rid of the distortion. It wasn't always to determine if the distortion was induced by hum or some volume setting.As it is now, I'm reasonably satisfied with the setup. I've been willing to settle with the difficult setup because of the price. Ultimately, this gives more options on setup than just using a bluetooth adapter.

Amazing for the price. Hooked up a pair of old Bose speakers and the sound is awesome

Lo recomiendo esta super bueno

High quality operation. Replaced older expensive amplifier
