It work, suction is good. Just don't like the vibration. It is a handy tool if you do lots of desoldering.

The first time sent the wrong address, wrote off with the seller, sent again, everything came, works

Delivery is very fast. Everything came well packed. I have not checked the work yet.

With large polygons there are difficulties, but in general it copes with its task.

Excellent Product!, it works amazing. I recommend it to 100%. Very satisfied.
