I needed a simple, inexpensive way to amplify classical guitar at outdoor weddings. I've only had the unit for 2 days, but I'm very impressed. It does exactly what I need it for - the sound quality is excellent and the 40 watt output is surprisingly loud. Ive only tested battery length for 2 hours so far, but I'm confident it will easily last for as long as I require and for me, the rechargeable lead acid battery is much more practical than having to use a new pack of alkalines for every gig.
Build quality seems very solid too and it's easy and comfortable to carry. I didn't buy it for the bluetooth feature, but I tried it with my clunky old Nokia phone and it paired very quickly, producing a rich, uninterrupted sound from about 30 feet away.
I would say it's well worth the money, especially with the 3 year warranty. The only cons I can think of are the lack of an output and the fact that you can't tilt it for use as a wedge monitor. Neither of these affect me though, so I am happy. Delivery was quick and efficient too.
