Good

I'll start off with some specs:-The straps are NOT 17 feet long like the item description says. It was actually just a little bit under 15 feet (about 14 ft 7 inches).-The rings are about 9 and 1/4 inches in diameter-The grip of the rings are about 3 and 1/2 inches around (circumference)With that out of the way, I'll say that these rings are great. The instructions are not perfectly clear on how to feed the straps into the buckle but on of the user images in the product images illustrated it as clear as daylight. This actually leads to the issue that a lot of people seem to be complaining about: the buckles. It's easy to ignore the instructions and try and feed the strap in the buckle using "common sense" however, that's more than likely the wrong way. If done in any other way than what was pictured in the user image I mentioned earlier, the strap will have a higher chance of slipping and causing you to fall on your behind of better yet, your face. It's hard to put into words exactly how the straps should be fed into the buckle so all I can say is look into the uploaded customer images in the product description page.Aside from that, I am a 135 lb male and I fully trust the equipment to be able to support my weight whenever I do exercises on it. The grips are not too big or too small. Also, the grips have a little bit of a texture on them so it's not very slippery if you want to do things barehand. Any type of workout gloves would be ok to use with it if your hands callous or tear very easily. Some reviewers suggest gymnastic chalk but I don't see the need to go that far and that specific.Also, it is true that the straps do not have any markings on it and this makes adjusting them to a perfectly even and matching level pretty difficult. However, this was easily solved with a ruler white-out. Just lay out the straps touching each other, side by side, and try to make them as even tip-to-tip as much as possible. then take your ruler and start marking by the each feet. I marked mine every 3 inches and wrote the number of feet whenever I come across a whole feet. This made a huge difference in how easy it was to start my workouts.Additionally, these rings are very inexpensive compared to "actual" rings they sell on like crossfit websites or something. It does what the other more expensive rings will do for a fraction of the price.All in all, I am happy with this purchase. It seems sturdy enough and I think that it'll last me a long time.By the way, this is the link to the picture that shows how to properly feed the strap into the buckle:

Have used these rings for the past decade. The straps and rings themselves have held up being thrown across trees, metal and more. Still holding up great

Very difficult but amazing pump and get used to them quickly, highly recommend.
