Works really well.
Used this to clamp/seal new axle CV boots. Works perfectly. No leaks so far. I have also used this on irrigation repairs.

Very heavy built, no questioning the integrity of this tool!

Works as intended
This clamp did the job just fine for me. There are cheaper ones on the market but beware, I have had one break on me before, which isn’t surprising since a lot of force will be concentrated into a thin sheet of metal. Lesson learned: go with this one and save your time.

Good to have for crimping cv boot clamps.
FYI, the tool was meant to be use for clamping while the drive shaft is out from the car. If you have to crimp the clamps while attached to the car. There is limited space the tool will fit. And if you need extra leverage you have to use two breaker bars. This gives you less room to work with while attaching the clamp with the drive shaft attached to the car.

It did what it needed to do
Its sad we need a special tool for a once in a decade type use, but it served its purpose.

Exact tool to buy
Don’t waste your money on the version from advance. Great tool too bad I may only use it a handful of times in my life.

It works!!!
Great tool. Make sure to buy one with the hex rachet attachment points. It comes in handy. I used a 18" breaker bar and 3/4" rachet with this clamp. No problems.
