This has been the handiest saw! I've had it about 2-3 years now. I imported it from UK Ebay - a friend there picked it up and sent it. I see it is now available from Canada. I can't see why this tool isn't readily available in the US.
It really runs smooth enabling almost full depth cuts - with limited access - plenty of power and speed and no battery running down.
The only problem I have seen with it is easily solved. If a blade breaks and the end is still down in the spring-release chuck - a small magnet easily retreives it.
