This encoder will give you 5-7k (max 10k) swipes before its magnetic head will be dead and unusable. I have experience i such things. Mine was bought for 160-170 EUR (i don't really remember) because i was searching for quality, not cheap shit, like you posted here. And as i said i am free for trading.
