I bought this for home use in order to; a) try and stop some of the lower frequencies escaping into my laminate flooring and disturbing the downstairs neighbours, and b) to elevate the amp and direct the speaker towards myself, rather than into my bed.
My amp is a Vox AC15C1, which is a rather heavy amp. I was confident on purchase that this stand would support my amp, which it does. However, my intention is to keep my amp on the stand for the foreseeable future (don't know if this is common practice or not). Upon putting the amp on the stand I immediately had the feeling that I couldn't move more than a few feet away from it for fear of it falling off. There is only one arm the holds the arms that hold the amp (if that makes sense), and as a result that is the only thing connecting my amp to the stand. It really didn't feel like it could take much more than I was putting on and I didn't want to gamble how long I could leave it on the stand.
The product I received was also quite warped, which didn't really help my fear of it falling. This meant that the rubber feet did not touch the ground, and rather the metal did which effected stability. The arm holding the arms (again, sense made?) was also bent, meaning that the amp sat at an angle.
I've had many of Thomann's Millienium products over the years and they are great value for money and really do their job well but if you want a stand to support a heavier amp, I'd recommend spending a bit more and getting a sturdier product.
