I had never heard of this product until now but Looking at their website, The main thing that jumps put at me its not an entire system. They say you can use whatever saw you want, an existing that you already own, why buy another?, Well, for me, Im a Festool TS75 owner. While ive only used a TS55 to compare it to, it depends on what you want to do with it. If you want to cut up sheet goods, youre going to have a hard time with this unit and a standard circular saw. One of the problems I see is, their track is 8 feet long. The same length as sheet goods. This would be OK if your circular saw plunges like a Festool , but none Im aware of do. So, how do you cut an 8 foot log sheet?. I suppose you can add length buy purchasing another section and bolting it in, I guess thats why they have a seemingly otherwise useless, 2 foot long piece?. Lets move on to adapting an existing circular saw to their "sled". Without any information on how this happens, this appears to be where alot of aggravation can come into play. For me, its alot like aligning a tablesaw fence to the blade without the benefit of the long tablesaw fence and Tslots to work with. The only alignment surfaces you have are extremely short ( the guide surfaces under the shoe and the circular saw blade). The slightest error here in being out of parallel would raise havoc to the final cut IMO. They have a section "comparing" their system to other and the only thing they really say is its heavier than others. Well I have a 3000mm long festool guide and I apprecite the lighter weight, although I must admit , I feel I need to be extremely careful with it.
