i know this is going to sound like a bizarre question but here goes !, i have a 3 minute UV lamp that is great for my colour gel but for my clear gel i should only cure for 30 secs ( otherwise it goes yellowy) i have a timer to time the 30 seconds but it does my head in cos it constantly beeps till i have a hand free to turn it off which is a pain when i am in the middle of another nail :irked:! does anyone use a timer and what is the flipping beep like !???
