Review on 🔊 Pyle Home Audio Power Amplifier System - 2X40W Bluetooth Mini Dual Channel Mixer Sound Stereo Receiver Box with AUX and Mic Input - Ideal for Amplified Speakers, PA Systems, CD Players, Theater Setups via RCA, Studio Use - PTA2 by Leonard Herrera

It took less than 5 months. Their guarantee requires you to ship it to Brooklyn at your own expense with a $20 investment, and if they determine it was their fault they say they will fix it and ship it back. In other words, it's going to be a warranty repair that'll cost you about as much as you paid for a new one. In the meantime, they have your $20 and the device, and you run the risk of it ever being returned in a repaired condition. This is the second unit of this type I have purchased from Revain and the first one failed around the same time. I was gullible enough to buy another new one, thinking there was a high probability that it wouldn't fail again, but it did. Do not buy.
