  • Great tool
There is a lot of power in this small saw. Cut through plywood like butter. Very easy to handle, no kick-back.

  • Impressive and powerfull saw
I bought this saw about a year ago (it’s actually my first saw), and it’s been pretty powerful. Back when I got it, I saw some reviews saying that bigger batteries were necessary to get the most out of it. At first, I was using a 5Ah battery, and it worked fine for plywood, studs, and general wood cutting. Recently, though, I decided to push it a bit further and tried cutting granite(yes, an actual granite countertop). That’s when I realized the 5Ah battery wasn’t enough. You could feel the resistance, and the saw just didn’t have the power to go through it smoothly. So, I got an 8Ah battery, and wow, what a difference! With a bigger battery, the cuts were flawless, fast, powerful, and effortless, obviously using the proper blade. I was already happy with the saw for regular use, but this recent challenge made me want to finally write a review. If you’re planning to use it for heavier materials, definitely go for the bigger battery and right blade. Overall, really impressed and glad I bought it! ... show more

  • Great tool!
This has become my go to saw for most of my work. Easy to handle and has plenty of power. Its just able to cut two by material and is very easy to manage on plywood cuts on walls for example since its so light. I agree its looks a little weird at first but I have grown to use my "axe"

  • Incredibly versatile small saw
I love this saw . It's not that heavy, because of size its very versatile and quite hardly any noise to it with alot of power and torque for a battery operated saw. Feels very durable. Worst part about it.... is the Allen wrench they give you to change blade. It doesnt stay put, you will lose it because it keeps falling off and barely snaps into place. Easy to install blade and saw dust is thrown though moveable chute out of way really like that myself. This is kind of pricey though, so $$ wise not a great value, BUT the real VALUE is its easy to handle and work with part even in awkward positions. I have a 9 amp/hr battery hooked to it usually and in a whole day of use never made battery go dead. They also give you a ripping guide also. No matter I still recommend it though. These tools are proven to be durable ... show more
