    Involvement Level: Expert (understands the inner workings)

    Pros: Small, yet quite powerful and very energy efficient. Runs fine on 12V solar power. Built-in volume control.

    Cons: Very small holes for input wires. Not possible to use in 'bridge'. Detecting L and R for input can be hard. You may need a heatsink, if load is 4 Ohms.

    Other: If you know how to handle wires into small holes on a PCB, this may something for you.

    Pros: Awesome! Just awesome. Such a powerfull amplifier for such a low price. Also low voltage, I use a 1A 12V adapter. I guess a 9v battery should work as well. Its really over powered when I really use 10w+10w. Can easily handle two 80w speakers :) just buy it!

    Cons: none :)

    Other: Awesome price/quality. I really recommend it. I

    Pros: This thing is amazing for its price, the yamaha chip is really good and for such a low price.

    Cons: The bass is not really spectacular but other than that...nothing really.

    Other: If you are handy, can solder, and have speakers. Then buy this thing before you buy a expensive one from a store.

    Pros: small, low voltage/power requirement. easy installation.

    Cons: nothing

    Other: another good quality amplifier to be used for satellite speakers or computer speaker. received after 24 days of placing order. packaging is acceptable. wrap in an envelope with bubbled plastic and another static free plastic.

    posted by only1humann on 11:32:10 G7T 02/07/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Tiny and Loud! I've had it hooked to three different speaker pairs and it sounded really well on all three. The speakers were 4-8 ohm. The amplifier is about 2.75 inches long (excluding volume Knob), just under 2 inches wide, and about .625" thick. I can't believe how much sound comes out of something so small!

    Cons: It would be nice if it was easily bridgeable to use two units in a 2.1 setup.

    Other: Many, Many uses for this little amp!

    Involvement Level: Expert (understands the inner workings)

    Pros: Easy to connect to speakers and power supply. No need for heat sink, at moderate use. Comes with a volume control. Build-in output filters reducing electro smog.

    Cons: Input location is not marked too well. Connection holes for input could be larger. They only take quite small wires.

    Other: If you need a small amp at, say, 5-10W in 8 Ohms, this may be it.

    Involvement Level: Expert (understands the inner workings)

    Pros: + price + it got a big buffer capacity enables decent bass + all pins are unsoldered, so you can integrate them easily in your designs + very good quality, enough power for every room or small parties + no noise when turned down + very efficient

    Cons: - just a small: the input is not isolated enough, the touchscreen of my smartphone is disturbed by the signal emitted/leaked by the boards design. But there doesn't seem any irreversable problem with that

    Other: great for DIY projects involving _decent_ sound, you get a fully usable circuit with all you need!

    Involvement Level: Expert (understands the inner workings)

    Pros: Have bought 3 so far. Quite value for money - Cheap, a 15v power supply for this might cost more than the amp itself - Quite loud, sounds quite good. Seems to be quite alright even at full volume. - Quite compact, smaller than what I expected. - Voltage range allows flexibility with using power supply. Used 2 spare power supply I had lying around.

    Cons: Cons - Not flat, bass seems emphasized. Can be a pro/con depending on personal preference. No bass/treble control, but at this price, can't really complain - Build quality. Out of the 3 that I've bought, one of them had a capacitor that dropped off. - A little troublesome to solder and fix up, probably due to the L/R/G being quite close and the surface mount capacitor that dropped out.

    Other: A cheap no frills amplifier that sounds great.

    Involvement Level: Expert (understands the inner workings)

    Pros: Very efficient it's slightly warm during operation. If you have 8 Ohm speakers and don't listen very loud it does not heat up at all.

    Cons: The big capacitor broke free from the glue on the board. But it's not really a big problem. It just moves a little, the leads are soldered OK.

    Other: I use it with old "Tonsil" 15 W speakers which are about 20 years old and the sound form my computer has good quality. And the can play really loud.

    Involvement Level: Expert (understands the inner workings)

    Pros: This tiny board can give a crystal clear sound. It's loud and gets barely hot. Superb quality for this price. Not a single noise while not connected to an input.

    Cons: Can be a bit difficult for a begginer to solder the cables needed for input (they are quite close each other, but for helping us humans, they've put some solder points away from holes) That's why i gave 4 stars to Easy of Use.

    Other: Package seemed a little flimsy, but it arrived without a scratch.
