I got this to run some higher end home audio speakers installed outside for the yard/pool area at our house. The speakers are $300 each and I had been running it on an older Sony coil-based home theater amp because I thought I needed the zones and independent volume controls/management for tone/eq. The amp in the cabinet indoors was putting out quite a bit of heat when it was powered on whether they were in use or not. The wiring was a total mess and I bluntly didn't enjoy dealing with it. I went in to this project assuming I was going to get a Denon, Onkyo, Yamaha, or some home audio mixer board + eq, or something fancy with roughly $2k budget... I was on struggle street trying to piece it all together. I only need a simple input amp. I have a cheap class T amp in my garage that works for what I am doing there, but the audio quality is trash. I rolled the dice and picked up a few of these and man, they blew my mind. They have a lot of punch/power and the audio quality is REALLY surprising compared to the old stuff I had. The BT connection is ROCK SOLID. A lot of these cheap china BT interfaces are trash and buggy. This thing pairs right up and is solid and reliable. I'm waiting on the splitters to feed the source to all of them, but per zone, they're superb. Super straightforward install and good labeling, pair with FosiXXX and go for BT. It's a small, light package and the box it comes in is pretty good for it's weight and has some heft. Not sure whether the weight is from the case or components, but it's a mosfet so we'll see about heat dissipation down the road and whether it does a thermal cutoff or not. I might end up getting more for the garage after a few sessions in the backyard. I was pleasantly surprised!

TL;DR: This works exactly as it should. Great piece of equipment is such a tiny form factorI've been meaning to setup a more permanent outdoor speaker solution to my backyard and was going to go with the old fashioned "run 200 feet of speaker cable" because the high receiver I bought was pretty far away and I was going to use Zone 2 for the speakers. But this little package came up on my searches and it was exactly what I wanted and more. There is an area in the backyard that we set up outdoor movies at and I use a portable speaker for sound. Instead it dawned on me that not only can i stream music from any source with this bluetooth connection to this device, I can also double up and use it for outdoor movies if I place them correctly. Well I found an outdoor telephone jack and indoor jack and I was able to run audio cable outside through those openings which were right next to where I would put the movie screen. So I was able to put two outdoor speakers in a place so that it can provide sound for movies AND they are in a general area that I can stream/play music for the backyard in general. No need to wire anything from the receiver and eliminates the need to bring out a boombox outdoor speaker for movies.What I was really happy about is how fast and solid the bluetooth connection is. I use an old laptop for streaming music and store all my ripped CDs. I thought I was going to have to hardwire the laptop to this Fosi amp because the laptop is like six years old. After a little work and trial and error, I finally figured it out and it works. The first time the laptop had a hard time finding it but now that it is in the list of known devices, it connects flawlessly. I tried iphones, tables, etc. and all of the newer devices find it with no problems. Even my echo show found it and its about 40 feet away in another room. Movies sound great, have my Lounge music running at night and I'm so happy about this setup. And, going back to my resistance to running cable, I only need 30 feet of outdoor cable for both speakers so it was convenience too.Highly recommend this product: very inexpensive, does exactly what it is supposed to and greatly enhances the flexibility of what you can do.
