I've been on the lookout for a new Amp for more than a year before settling on the Rocker 15. 
After having used my Peavey Vypyr for about 8 Years, I wanted a low wattage tube amp. 
Out of a few british amps at a similar price point I liked the sound of the Rocker 15 the most. 
 
My first impression was basically "wow that thing is LOUD". 
I play in my flat and even though I use a silent cab, I still run the amp at one watt most of the time. 
 
What I like: 
* A nice range of sounds from crisp cleans to quite high gain 
* The way it reacts to my playing 
* The ability to dial it down to 0.5 watt 
* The effectsloop 
* It takes gain pedals quite nicely 
* The simplicity of the interface 
 
What I don't like: 
* The channel switching footswitch is a separate product not provided with the amp 
* I think the highs of the dirty channel could be a bit more focused (is almost a non issue, but I thought I should mention it) 
* There is a switch between half and full wattage on the front, however the switch between the "headroom" and "bedroom" settings is at the back. This could have been moved into a single 4 way switch at the front. 
 
What to expect: 
* An out of the box good sound, just plug it in and it will work 
* A good base for pedal usage 
* A loud amp that can easily keep up with a drummer 
 
What not to expect: 
* An absolute high end metal beast 
* A quiet amp, that can be played in your flat at night (to be fair it can do that, but not at optimal sound) 
 
Regarding the features: 
* As previously mentioned I would have liked the footswitch to come with it 
* You receive a nice bag for the amp, which is adequate, considering it is not that heavy 
 
Regarding handling: 
* Most of the front is described by pictograms instead of text, that might initially not be intuitive, but for a quick look it works a lot nicer and makes the front look a lot cooler. 
* The clean channel has no way of adjusting the sound, however I don't think it is necessary, it already sounds phenomenal 
 
Overall I am absolutely happy with my purchase and for my current situation it was definitely the right choice.
