Review: Works great - Worked great. The only thing I would recommend is having a lighter (or torch) to heat the ring. And then a screwdriver to help get the piece off afterwards. But helped bring my ring up like 1/4 size for comfort.
Review: Good tool to have for Jewelry lovers....Easy to use! - Had several rings that over time got a bit too tight to wear. Purchased this to take a chance at ring stretching on my own since the jewelry store has gotten really expensive to go up a half size on ring-sizing. Worked like a charm and was really easy to use. Learned that it works best on a piece of full grain when tapping to stretch unlike hard surface without cushioning results. What started out as a "give it a try" item ended up being used for all my rings that were too tight. It should be noted that this is good for going up a half size and up to 1 size depending on the thickness of the jewelry ban. men's rings tend to be thicker so I had no issues however have not tried it on a ladies ring. Also, this cannot be used on rings that have stones that are mounted on them as they take a different type stretch unit. Definitely would recommend and will buy again if this one wears out and I need another one.

### ⭐ Simple wedding band almost destroyed
*by J***S on August 25, 2024*

I watched the video and followed the instructions precisely, hoping to give a minor stretch to my simple gold wedding band. After tapping the top part as described, I could not pull the rod out of the mandrel (the stretcher) and thus could not release my ring. I had not hit the rod hard, just tapped it as shown in the video, but it was completely stuck. It tried pulling it out with pliers, to no avail. Finally, I put one end in a vise and used pliers to turn the other end, and after much sweating was able to separate them and rescue my ring ... which had not even stretched at all! In the video, they do not show this step -- removing the rod from the mandrel. It just skips forward from tapping the rod to pulling off the ring as if by magic. I repeat: I followed the instructions exactly, but after an hour of wasted time, and much anxiety for my ring, this was the result. And now, I still have to take my ring to a jeweler to stretch, compounding the waste of money. I do not recommend this product.
