A good pot for building stuff and repairs'!I build music-synthesizer equipment and I personally like 'high-end' pots',but the price of those has gone 'out of sight'!These pots' are probably rated ,modestly at '10 thousand-turns'!I also like the 'rubber boot,dust covers' for these.Those will keep the grime out,for a bit! : )
