I am not impressed with the dust management of this saw. I taped over the little window but the 2019 version of this saw spews dust forward even when the dust port is connected to a festool dust extractor. I bought it to see if I would actually use a tracksaw much, so perhaps it is time to upgrade. It seems a shame as apart from being a little jerky when setting the depth etc it cuts rather well. As it is an 8th of the price of a festool and nearly a 10th of the price of a Mafell, well actually the entire saw is almost the same price as a saw blade for one of the two I just mentioned it is a great tool for occassional users. So if anyone has a solution to the forward spouting dust issue I am sure others would be glad to learn about it too.
