Excellent value for the cost.
O.K. I'd read all of the reviews, especially the negative ones, and still chose to buy this one (Amazon has a great return policy, just in case). Unlike the negative reviews, mine was not rusted, it did not leak grease, did not have defective hardware and was packaged very well. My first usage was to turn a size 13 coin ring into a size 4 - my first time using such a tool I should add. It worked great! The rest of the day, my daughter and I took turns cranking out rings of various sizes with no issues. I learned that when using the stretcher, it's best not to try to go full swing with the lever but stop at vertical, pull it back, turn the ring 1/4 turn and repeat (otherwise mine tends to bind up when the lever is pushed past vertical). This unit beats paying over $400 dollars for the Cadillac models IMHO.

Ring stretcher and reducer
I use this item for my ring making, it is easy to use, great quality. The material is great quality.

So easy to use!
I’m so impressed with how the stretcher worked. I was nervous to use it on this beautiful ring that belonged to my mother as the shank was pretty thin already. But it didn’t take but a light press to just it perfect on the first try. So happy!

Overall not bad.
Adam arrived as described sort of there was no size markings on the mandrel for the enlarging or the shrinking of the drinks there's nothing laser etched on the manager whatsoever to give you an idea of what you're working with haven't tried it out yet we will see what happens when I do that.

Very impressed as soon as I opened it.
I was a little skeptical about purchasing this ring stretcher/reducer because it was so inexpensive, however I feel that it is very good quality, no roughness inside the ring reducers or on any of the metal, and the ring stretcher is absolutely perfect and high quality as well. I especially love the fact that you can stretch a very tiny ring, as I have watched video where a YouTuber purchased one and you can only stretch larger rings as the tip was too large to fit a small ring on it. It is very easy to use and seems just a nice as the expensive ones. I highly recommend as you can't go wrong, especially if you are just starting out or on a budget. Don't hesitate, just buy it, you won't regret it!

Super easy/intuitive with minimal chance of messing up. Did not mark rings
Had to enlarge a couple of Wedding Rings. After, enlarged and reduced friends' rings. No problems at all.Does not mar texture of band, nor stones embedded into band, but stones that reach beyond the edge of the band would be damaged by reduction, and soldered mountings might be damaged when enlarging.

It’s ok
I bought one previous from the same vendor on Amazon. It worked well until the hand held lever broke. It is cheaper in price compared to others. I ended up buying another one from the same vendor

Great for the price point
Works great for resizing ring shanks, only suggestion would be the ring sizing measurements on the mandrel itself are not correct, so need to compare against an accurate mandrel. Go slow and work your way up/down to correct size
