I've used a variety of different combo stands before, most are generally cheaper than the K&M offering, but after using K&M guitar stands and speaker stands for a year, I thought I'd give the amp stand a try for my Fender Supersonic Twin. Like most K&M stuff it's very well engineered and thought out and doesn't have any of the annoying problems that so many stands seem stuck with.
It can be folded up extremely small, as small as a short mic stand, which is better than the big 'folding deckchair' designs of many amp stands. It's design allows you to alter the tilt angle and lock it in place. It takes a lot more weight than some I've used without looking like it's going to fall. As the Fender Supersonic Twin is about the heaviest combo in the world this was pretty important to me! The ability to add in an arm to mic up the combo is very neat too.
I've not been using this long but it's already convinced me to ditch my other stands and just stick to K&M for anything like this.
