Xiem Tools 12 Inch Batmate From  £12.85

This is fantastic. Obviously not essential to the life of a potter (and I favour poverty stricken methods - it feels a bit more 'true') but a luxury item that I don't think I'll go without now. It will save on buying batts to replace my warped and slightly knackered ones because it does indeed minimise jitter and wobble.

Almost too grippy. I use these with a bat insert system and it works almost too well. It can be tricky getting the insert out.

Using with regular bats works very well.

previously wobbly bats now stuck to the wheel head like glue. Superb!

I think these bat mates are excellent they are constantly in use.
