Buying a lactate meter

I’ve been thinking about getting one myself to tinker with, and I came across this one

Does anyone have any experience with this one or does anyone have enough experience with lactate meters to determine if this is good enough to do some tinkering with? I understand a Lactate Scout 4, which is probably used the most by both pros and amateurs, is probably better but it’s also 3-4 times the price…
