As with any tool on the market, circular saws are found in a variety of models. The best circular saw allows you an easy adjustment and perfect visibility of the cutting blade because if you do not see where you cut, you can not cut too precisely. The best saws have alignment accessories and cutting indicators to ensure flawless operation. I found different saws that are good and perform well, but when I looked at the price, I said a bit, and I did not buy, and I can not say which are the best.
