COMOWARE Step A very useful tool: my truthful feedback

Hello readers of this review. As I already wrote in my reviews, my job is to maintain and repair various equipment, mainly at the customer's site. For example, I service equipment in school canteens, in some of them the old Soviet equipment was decommissioned five or seven years ago and a new modern one was installed, some have Soviet equipment, and so in equipment that is five years old, sometimes there are more malfunctions than in equipment that is thirty-five to forty years.

Pros
  • Comfortable, versatile.
Cons
  • It's still dull.

Pros
  • 1 (ten in one)
Cons
  • Long time coming from china...

I've tried everything and this is what I can say. In the store opposite, you can buy a set of drills for this money and throw it away immediately without drilling a single hole ... and this Chinese miracle works quite tolerably. I drilled 4mm aluminum, 1.5mm steel plates and thin sheet material such as tin and stainless steel, the…

Pros
  • Compactness, price, tolerable quality
Cons
  • They are still dumb
