I've bought this stand mainly to hold my electric guitar in my bedroom, about 5 months ago.
It provides adequate stability, even without a neck support, and it´s trustworthy enough for me to just place my guitar in the stand and not worry about it, tough if I had the stand in a place with more movement I might worry about my guitar falling off if someone bumped into it.
The only real quality problem that the cushioned support that holds the bottom of the guitar is weak and deteriorates fast. I guess that with accustics guitars it might hold well, as it did for mine, but it doesn't cope that well with the heavier electric guitars.
Despite that, I'm quite satisfied so far, especially for the price, and I do recomend for someone in a budget. Just be watchful for the wear in the material if you are mainly using it for electric guitars.
