VT-168 Professional Multi-Function Rechargeable Voice Amplifier with FM/USB - Dark Grey

Pros: I was pleasantly surprised with this gadget. First of all it works, it makes your voice loud and relatively clear if you have the mic close to your mouth. It has a nice echo-function not avaliable on other similar devices. Good MP3-player that supports vbr. Just plug in a usb -stic and it plays your mp3-files (both on root and - after that - in folders). If you hold the play-button you have a repeat one and repeat all option, and a auto-search and auto store-function on the (not so good) FM radio. The built-in battery pack has two seemingly good quality 18650 li-ion batteries and is equipped with electronics, supposedly for protection (against over/under-voltage) and probably balancing. Good! The build quality is good, you can drop it!

Cons: The cons are that the "25 watts" is 3 watts. The amp is a simple 4 watt bridged IIC TEA2025B (hidden under a tiny heat sink. The speaker is a simple YDS 3Watt. The amp IC is a TEA2025B. Gives 3-4 watts (bridged). The speaker is a 3W 4ohm cheap DSY with a decent magnet, meaning it is loud but heavy and will not stand very high drops to the ground...

Other: Good, worth the price, 3 loud watts (not 25)

Pros: Allows you to talk down in a classroom with 45 or 50 students. Very good input usb pendrive to music also has FM radio and auxiliary input very useful for use with notebook and other equipment. It also has a button to control the feedback.

Cons: The indication output power of 25W does not match what you hear when at maximum volume, it's still very good. The cost-benefit of this product is significantly good.

Other: To get more full must accompany cable for auxiliary input and Memory card slot. Less necessary but also important would come with remote control. I recommend the product. Thank you!
