I had a problem cutting tiled panel in a built together, and did not know how to solve it with my usual tools (hand or jig saws, drills, chisels, hammers, ...); I found this tool on the internet and bought one that seemed to offer the best price / quality ratio (you still count yourself buying replacement blades because the departure provided blades are few: those -C are pretty standard and you can easily find compatible blades at reasonable price), and I must say I am not disappointed: the operation on which I thought I had to spend two days with a lot of damage has been done very cleanly in 2h: very fine blades were able to pass between the tiles without even touching them, cut lines on the wood are very clean and very thin, I can easily reposition the panel without having to re-tiling work , plaster, etc ... I do not know what will be its durability but for now this tool has fulfilled its function perfectly and I think it will serve me often
