actually really incredible sound for the price

This little thing is the most unassuming but solidly robust amp I have had. It creates a full and rich sound without leaning too hard on the bass. It's just such a simple, solid product. I absolutely love it. I use it for music a lot, but also I have it connected via bluetooth to my Apple TV and I have never had a single latency issue or sync lag or anything. It's phenomenal.

Better than expected

So far so good. I got this to connect my TV audio to existing in-wall speakers without adding a large amp. The bluetooth connection is solid and it was easy to pair with the TV. The sound quality is good, wasn't expecting audiophile quality for the price, but was pleasantly surprised. I would recommend this to anyone looking for a easy solution for bluetooth using existing speakers.

Using in my RV

The RV came with an odd car stereo that had seen (heard?) better days. I'm using this as a temporary replacement ... but it's working so well that now I'm in no hurry to decide what I want for a replacement. Connected to the "car" (4 ohm) speakers and the sound is very satisfying and plenty loud for the RV space. (The "Blue" is at half volume setting and adjusting the Bluetooth volume on the source device gives whatever volume we want.) Yes, I've had audiophile quality systems: audiophiles look elsewhere and in any event, the speakers are the critical elements. It is connected directly to the old stereo 12V wiring, no AC converter. In this setup we need to use Bluetooth: hard wire from another 12V-connected device produces a loop hum (which can be eliminated with another device ... use Bluetooth & save the money). If the Bluetooth source/transmitter is behind a wall or two, or object or two on a table, the sound falters. Not this device's problem because it's in clear view. After the new car stereo is purchased, this will become the amplifier for a computer/movie TV setup in the RV.

Fantastic Value

Runs cool. Plays loud. Sounds is clean. I opted to use my own power supply rather than the cheap one that comes with it. Only annoyance is the startup and shutdown tones. They are too loud and too obnoxious. Tone it down. Make the sound pleasant. Don't let it play over a certain soothing decibel. Alexa Fot, for example, has nice sounds to indicate device status. The JBL Bluetooth speaker I had broke and it cost almost $100. I went to the thrift store and picked up some bookshelf speakers. Now I have a super nice small room system. It lacks a battery so is not portable but I rarely took the JBL places. The Alexa Dot is programmed to turn this on and off using voice commands. I just love it. This eliminates the annoying shutdown tone! But I still get the startup and connection tone. Eek.

So far it works well

It is too soon to give a review buy with my initial testing it works well to what I intended it to be. One reviewer mentioned about mounts--yes there is no way to mount it. I was thinking of double backed tape or adhesive velcro for a non permanent mountings. As long as it has stars, on my review, it means it is still working well because I always update my reviews. UPDATE: Still loved it to this date (2019), thinking of purchasing another. I concealed it under an outdoor sofa with one of my old outdoor speakers. My guest loved it and are wondering where the sound is coming from. Mounted with velcro and tiewrap under the sofa, set it to always on, full volume, but the power plug (12v PS) is controlling to power it. The lady speaking when you power up tells me that it is ready for connection (it worked to my advantage. I use an old iphone 4S with selection of thousands of music for any generations to pick from which also controls the volume. Sound quality is amazing and matched the speaker so well even in full volume. Cannot complain. Only problem is do not tell your guest that its bluetooth or everybody Will request to use their own music, then you will not be able to control the volume. It is also the cheapest anywhere I checked as of this writing. I used a 12v 3A PS, from an old AT&T router. It worked well.

Great value

I wasn't sure what to expect from this little guy, especially at such a low price. I have a pair of extra speakers that have been replaced in my living room, but I thought I could put them to work in a different area of the house. I plugged them into this unit, and it worked great right out of the box. My phone found it right away, and I was up and running in no time. I'm not really an audiophile, so I won't comment on the sound quality, but just to get set up on real speakers via bluetooth for a low price was a win for me.

It's small and has sufficient power to for my application

I'm using this to power a pair of 3inch speakers in an ammo can boombox build, in combination with a lithium ion 12v battery pack I also purchased on Amazon. It's small and has sufficient power to for my application. I would buy it again for other projects.

Good product.

It has a good power. I have not connected a Bluetooth yet but the manual book did not mention anything about a Bluetooth connection. So far so good.

Highly Recommended for DIY Projects

I used this inside a vintage suitcase that I installed vintage speakers in. What I like about this unit more than some others that come as a bare board is the power up sound notification is pleasant, rather than a loud voice saying "The Bluetooth is on" with highly-accented speech. It seems to be well-built and feels solid. The speaker screw connections work well. Reception is great and I am very satisfied with the purchase. I will be buying more of these as I sell more of my projects.

Small, powerful, efficient, easy to carry and setup stereo amp - until it doesn't work.

Volume control is nice touch. It's driving 2 heavy (14 yr old RCA) bookshelf speakers from the amp, using BT from iphone and Win 10 PC. I love the power input range 9V up to 24V DC. I took an old 16V 75W DC laptop power supply and plugged power in to the amp. Speakers on my desk sound great. My family upstairs thought I was having a party! Loud, soft, no distortion. Case does not get hot. For $23 (w/o power supply) I like it! Update: after working well for 3 days, it just shut down and won't power up again. I was listening to music at mid-volume and it just stopped. The amp was warm and it smelled like something inside is crispy. Power input says 9-24V. I gave it 16. I will be returning for a refund.
