Evolution ST2800 Universal 2.8m Circular Saw Track (1400mm x2) With Connectors Guides are ok although one track may be a bit pinched as it is difficult to get the connecting rod into it when using two combined for a longboard. The carry bag is a great idea to keep everything together however it is a very tight fit to get the tracks in so much so the bag is already coming apart after just two uses. The hex key is just a small standard hex key and I can see it will get lost very quickly it would have been much better to supply a key with a built-in handle or creating a safe storage place within the clamps to retain the hex key.
