## Customer Reviews

### ⭐⭐⭐⭐⭐ Amazon and KwikTool very helpful
*by B***. on July 1, 2011*

My original BBS450 arrived damaged so I returned it to amazon for a refund. In the meantime I contacted KwikTool and they have bent over backwards to help me.The BBS450 wouldn't work on my "old" Makita model 9505B (I've had it for over 30 years). KwikTool made every effort to get me up and running and I ended up with thier Hurricane kit(HK450).I was glad and surprised to see a company take the words "service and reputation" seriously in this day and age.The "Bad Blade System" is really a great idea. I saw it when I needed to replace some damaged flooring in my older mobile home and could see that this would work right up next to the wall to cut the old flooring out.Kudos to KwikTool for an inventive and great tool and a support staff that actually tries to help you, thats rare now-a-days.

### ⭐ i bought this to cut pallets with nails and the blade does not last long at all i had much better results with a demo blade on a recip
