I purchased this drum riser to replace the one that came with my Ludwig Breakbeats Kit. The Ludwig riser snapped after a years worth of gigging. I found that it was temperamental and difficult to use.
The Gibraltar riser however is the complete opposite. Not only is the build quality a lot better, it extends further, tightens easier, and has a better rubber grip for the bass pedal.
I use it to lift a 16" bass drum, however it does seem strong enough to lift any size bass drum.
This riser is noticeably heavier than the Ludwig version and I would therefore recommend taking it off of the drum when packing away. I was able to leave the Ludwig version attached to the 16" kick as I knew there would be no strain on the drum hoop. With the weight of the Gibraltar riser I can imagine it putting some stress on hoops when packed away.
I would highly recommend this riser. I've certainly had no issues with it. Note that if you do purchase this riser, you will need an Allen key to tighten the hoop clamps.
