The tool is fine. The case is garbage and doesn't keep the parts in order. The tool will do the job, but the parts don't actually fit in the case like in the picture. Good for a one-time DIY job. You'll spend a lot more time digging through the various dies to find the right ones than using the tool. For professional use, spend just a few dollars more on the Mastercool brand equivalent. Your bank balance will thank you. Even if you already have this item, better to buy the Mastercool which comes with a organizer/box and keep the Vevor as a set of spare dies in case a cow-orker loses one of your dies.
