Bought this for my classical guitar, which does have quite a large body, but a shorter scale neck.
I've got a myriad of Hercules Stands, as I've always trusted them above all others to be rock-steady for my guitars. They're built well, with high quality fixings, and there is nothing to complain about the quality of the products.
The design is perfectly fine for acoustic and classical instruments. My classical guitar isn't too expensive, and it supports it absolutely fine. I'm not convinced I would trust it to hold my more expensive electric guitars, nor an acoustic with a longer neck.
I wouldn't say this is a good idea if you have children or pets running around your house either; if the guitar is knocked it will fall off this stand!! If you're guitar is your pride and joy, I would certainly recommend going for the Hercules Stands, with a locking neck support. Same really goes if you're gigging alot, and there's going to be alot of people walking past the guitar around the stage.
However, it really does what it says on the tin - a small guitar stand, which has the benefits of being able to stick in a gigbag, which doesn't cost the earth either. Overall worth buying, but maybe for cheaper instruments, as a travel companion, or a backup for another stand.
