Behringer Powerplay P2

P2 is a much better than a P1 amp in both: size and power.

It is much more comfortable to use it for a standing setup, because, it is not as bulky as P1. If you make a custom cable 2 xlr mono > 1 xlr stereo it works as a stereo amp flawlessly. And thats the only thing that is better on the P1.
Power of the amplification and the power consumption is way better than it's bigger brother. 9v batteries on the P1, can hold not more than 1/3 time of this AAA battery setup.. Its superb. Quality batteries hold up to 10gigs (±2hours of playing thru the night) for me. While the P1 is not as loud and powers up on a single battery only for ±3 gigs..
It has a good headroom (much more louder than a P1) for playing with a loud band and setting up a powerful headphone mix.

2 things, that could (and should) be improved:

1: Though the format is small, its not very VERY strong. I have had used it for 30-50 gigs already, always clipping it to my jeans strap, sometimes sitting on a chair, sometimes standing up, and, it's chassis has a dent around a XLR area, and a belt clip has a little lost its form.
This does not effect its performance in any way. Just it could be a little stronger.
2: The batteries, more than a few times, after a transportation have had fallen from their places, so almost 2/3 times, out of 4, after you arrive at a gig, you have to open it up and reattach the batteries in to their place.

Price - makes it a no brainer.

Would I recommend them? Why would you even ask it! Would recommend it by 150%. It is a must have for any gigging musician. Just to have it in their backpack with a cheap set of in ears (for example KZ ES4), if the venue is too noisy/loud/not enough monitors/not working monitors - you can save your day for a ±50eur and hear everything loud and clear.

Been using this one for a year and it was good experience so I decided order two of this, they are reliable and I've seen drummer who used the same model in the stadium playing show so yes this one proved to be good thing with surprisingly low price
Pay attention to switcher inside for mono and stereo connection
From factory they are coming switched to stereo

My advice, use good quality batteries not the cheapest, and don't forget after soundcheck turn it off to save battery

Behringer has been producing good equipment for some time now, and this is no exception. I use this as an in-ear amp at band rehearsals and it does the job just fine as the actual sounds depend on a multitude of other equipment, so it's hard to really weigh in on that.

The build itself is good and it's really robust with an accessible battery for quick changes, however, I think that the buckle is a poor design, not the quality, that's good, but the design and the placement are not really functional. That might not be an issue for everyone, but it is for me and I would like to see a better option in some newer designs.

The build quality is good, solid and the housing made of metal is a good feeling. The overall product is in my opinion a bit on the rudimentary side. I know it doesn't have to be fancy as it is functional but it is very rough and ready, clicky, like a toy almost. Changing the 2 AAA batteries is a bit nerve-racking as you have to actually slide open the body pack, revealing the electronics inside. Yikes! It has made me nervous a bit. There's a mono/stereo switch inside the casing also next to the logic board, and it is a bit basic here too.
Sound is solid. Overall there's nothing fancy in this product and the price tag is very attractive for what it is. It does the job, well, but if you need a bit more refinement and probably extra features, like a second output, or a better belt clip, or a "less scary" access to the battery compartment, look somewhere else. If you however are looking for a cheap and cheerful, ready to go simple body pack for your In-ears, this will do a grand job !
