I was looking for a light router to do some furniture assembly work in my RV. So when it was in stock I ordered it. Here's what I found: 1. First, the statement is nonsense. It is not clear, does not really apply to this tool, no information about the use of nozzles and maintenance instructions, it seems, for different types of equipment.2. Turning on the device involves a very strange switch. Not what I would recommend. In any case, as soon as the device is switched on, the speed keeps changing up and down and does not reach a constant speed. I highly doubt the 30,000rpm claim. After it worked for 30 seconds, the unit's case got warm. Considering he was not doing any work, this should NOT have happened.3. The cutter in the device is easier to operate with real tools than with the punched parts supplied. Once installed and tightened, DO NOT TRY with a regular cut! It will stall and stop! Do many passes for what you would do on a normal router in one pass.4. The device gets quite warm even with little work.5. The clear plastic base is cheap, feels cheap and I doubt it will last long. All edges are rough so watch your fingers. In my opinion, even for a disposable tool, the purchase is not worth that much money. This takes longer and creates a rough surface that a tool running at the right speed could not reach. The extra time you spend getting this task done quickly will pay off in a better tool. I would not recommend that.
