One of the best comparators around, cheap and nice fits right in and I would recommend the IC for any modern day child who wants to fix their mobile phone. I bought one of these and boy it was amazing, worked like a dream and I would happily buy them again as I could easliy slot them and it gave me much joy in doing so!
