I bought these suction cups with a bit of skepticism based on some of the reviews. For a year and 4 months none of them let me down. I just finished 1 before this review. They get the job done and I've used them on a variety of projects from replacing mouse switches to replacing analog sticks on game controllers to replacing capacitors. I will say that it took me a while to master using a solder sucker in general, but one day I realized that these things work great. The included desoldering braid is terrible though. but at the price for 3 suction cups it doesn't really matter.
