Haven't used it yet, but in hand it seems to be a pretty decent little saw.
Seems to be made from good quality materials. Good handle ergonomics, feels good in the hand. Adjustments are easy and smooth. Excellent saw for the price. Deffinately would reccommend to anyone in need of such a saw. Very good deal, comes with 144 blades also.
It Is a very strong tool, made of metal, it allows you to adjust the correct size by moving the upper part of frame. Also pieces of saw blades are perfect to make cuts as I need to do.
