I never had any problems with my UJK Router lift, I had it in a extraction enclosure and used the recommended STP oil/grease on the chain, never fouled up or stuck in any position, hope others keep slating it as no good as since selling up in France and leaving most of my tools behind I am in the market for another and would not hesitate to buy one again for the right price, I do like the look of the Jessem though, engineering wise the four post lift is superior to anything with less.
