Two days later I had my glass and ordered ground pliers in front of me. Solid tool, orderly and stable processes, the first impression. The second was even better: I have attached the matching plastic inserts - clock, inlaid floor cover - click! That's it! The pressing of the soil lasted max. 2 seconds. An ingenious tool - batteries, watch glasses, seals change I to wristwatches only himself. It pays up to use a professional tool!
