Well, I've now had two of these break on me. I honestly can't recommend anyone buy this. I have a similar one (same wire grip design) but with a plastic handle made by Ducky that's still going strong -- even though it's been used more than the other two combined.
arithonI have a Filco keypuller with a plastic handle that has stripped probably fifteen full 104 key keyboards with no issues.
This looks a lot like the MKC keypuller which was also total garbage.
First one broke after removing 2 keys off a Filco MX Blue, the replacement broke after pulling 8 keys.
