  1. Great tool I bought this to replace a Dremel multi-tool and I couldn’t be more satisfied. This Sonicrafter puts the Dremel to shame. It is quieter, more powerful and cuts much quicker. I purchased the Hyperlock model to take advantage of generic cutter heads and it doesn’t disappoint. For the price, I would rate it equal to the more expensive brands of this type of tool.

  2. Great product I have a Fein tool and needed to get another because I have a large crew. I do remodels of kitchen and bathrooms and use the Fein tool on every job but needed another and did not want to pay the price for my crew to abuse so I bought the Rockwell and I hate to say it but I really like the Rockwell better. It accepts all blades and is super easy to change out and cost savings is huge as you know the prime cost of these tools are the various blades etc. Get it.. you won’t regret it!
