Which desoldering pump to choose? Great review

This time I decided not to choose for review some thing worth $ 20-30, but to order a few inexpensive, but necessary things for every radio operator - these are desoldering pumps. 4 desoldering pumps from China, among which there is the most popular and cheapest option, as well as expensive models. The main question is whether it is worth overpaying 2, 3, 5 times, and which desoldering pump is the best. (of those in the review)
