I switched out my RRS lever clamp for a Hejnar screw clamp on my small tripod after the second RRS lever clamp I bought began acting as badly as the firstWould you care to be more specific about how they began acting badly?
A side note on lever clamps: they can be finicky with the camera/lens plates used as they have to be built to tight tolerances--usually they only work with the same brand plates +/- one or two other brands. Mixing brands can lead to headaches. Hence you may want to buy a screw clamp.Yes, except compatibility isn't guaranteed even with screw-on clamps. :-(
I've got two RRS clamps on two different ballheads, an old one (bought almost as soon as they started to make them) and it still works just fine but (as advertised) only with RRS plates, and a brand new one, which is slightly different and clamps securely with every plate I've tried - including one that most screw-on clamps I tried won't hold (it's too narrow).
A recent dpreview ballhead comparison tested their clamps as well, might be worth a read.
