I bought this because I was looking for a circular saw that had dust collection. The only other option is a Porter Cable, but their customer service was non responsive while Evolution was easy to reach and helpful. From the pictures I thought it looked rather clunky, but it is more impressive in person. It is well balanced and easy to guide, even one handed. The built in dust collection will collect about 75% of the wood dust or metal chips. After a few cuts it is full and has to be emptied or the dust just spews out like every other saw. It also has a dust port that can be connected to a shop vacuum. In order to collect as much dust as possible, the blade is fully enclosed by the blade guards and this makes it harder to see the actual point where the blade is cutting. To help with this issue, Evolution has installed a plastic view window on the left of the guard. I find that this works fairly well and allows me to see the cutting line although I have to wipe it clean with my finger before the cut.
I have tried it on dry wall, wood and angle iron and it does everything with ease collecting dust and with no apparent blade damage. It is geared down to give it a slower blade speed and thus more torque. Evolution says that it produces few sparks cutting metal and they are correct. It comes with a roomy plastic case, an edge guide, a vacuum dust port and a rather useless DVD.
One thing that nobody seems to consider is the power use. This saw takes only 10 amps which means that you will be able to use a longer extension cord than a saw that uses 15 amps.
If all you want to do is cut clean wood as fast as possible, then this saw may not be for you. If you need a saw for multiple purposes and especially if dust collection is a plus, then consider this saw. It is much easier to cut metal with this saw than an angle grinder with a metal cutting blade.
