I had a job to get done, some commercial shelving, and decided it would go much faster with a track saw instead of trying to use the TS for cutting full sized melamine and slat wall sheets. I had already been looking at them so it didn't take long to verify I wanted to go with the Makita due to price and the reviews on it. Here are my thoughts after using it for a few days;

1. I like the fit and feel of the saw. Seem well designed and comfortable to use. The buttons for changing depth of cut, the scoring function, etc. were well placed.
2. I love that it is variable speed. I used it pretty much on the 2 setting so it ran slower (instructions said that the blade will last much longer if run at slow speed), but more importantly it cut just as good and was so much quieter than a standard skill saw.
3. The first time I used the plunge feature, I got a small amount of kickback, but it was my fault for not having it firmly held. It was the only time as I learned to respect it a bit more.
4. The cut on the under side, (melamine) was clean. The top side was pretty good, but not as clean, unless I used the scoring cut first. If I did, it was incredibly clean on both top and bottom.

Now the bad, what I don't like.

1. I am sure on wood sheet goods, the track will stay right in place, no problem. On melamine, it was alright, but not perfect. I had to be very careful not to bump or nudge the track at all. When cutting, I had to carefully push straight forward with no side pressure, or the track would move. I have ordered a couple of clamps to help with this in the future, and I realize that perhaps nothing is going to hold on melamine since it is so slick. It was better on slat wall.
2. I didn't realize, perhaps lack of attention on my part, that it does not come with a dust bag. Seems a no brainer that they should just include it. Oh well, a minor point.

One last note. I read where others use it on the floor, using a piece of dense foam for a cutting platform. I liked the idea so picked up a 2" sheet. I don't know how they do it on the floor, but it was beyond me. Trying to cut on my knees was never going to work. I pulled out a couple of cabinet saw horses, ones we used at the old shop, then put two 18" full length strips of 1" melamine on top of those to act as supports, and used the foam on top of them. That worked great. I also realized that it gave me a sacrificial platform for drilling. No need to worry about going through to something below. Made drilling some pilot holes, etc. much easier. It was a great way to work, yet another tip I picked up reading SMC.
