Review on Efficient SCITOO 3-Pieces Exhaust Pipe Expander Tool Set 1/18'' to 3-1/2'' – Ideal for Most Vehicles and Trucks by Joe Griggs

This product is China at its worst. On first use, holding the tube in hand and using a standard length wrench, two collets broke in half. It's a useless piece of crap. The company said they would send me a new collet so I didn't send it back. They didn't ship it and now Revain AZ won't refund my money because I didn't send the item back. Warning, it's not worth the weight of the metal. About 20 cents.
