I have trouble with them. I believe it's mostly the fault of my students for not treating them well and partly me for not teaching them better. Here's the trouble I have. Please let me know if you have similar trouble, know of solutions or know of a better model/company to buy.

The T-bolts fall off and get lost.

The legs won't slide even though I've greased them two different ways. I assume this is caused by small nicks and dents from kids mistreating them and/or dirt and grit getting in the tracks. I bought the bag cases one year to mitigate the dirt issue but the top half of the bass drum stands don't fit at all.

Despite the fact I know how they operate stands, they tend to fall over because they're imbalanced.

Plastic feet pop off.

The 4-claws of the bass drum stands fit no bass drum I've ever put on them, any brand, any size. Not really. Kinda, but not really.
