How well does the pump work? A couple times I've had to desolder a connector or IC with lots of pins from a PCB and it's a painful process. I've always wanted to buy one of those, but I've seen lots of reports about getting clogged easily.

I rarely desolder, but I can easily justify a hundred bucks if I can avoid all that hours of work, where I'm also risking damaging an IC, lifting a pad, or something else...
