When I had first taken interest in kegal exorcizing about 5 years ago, this was my very first set. At the time, I had read lots about them and I thought I'd benefit most from the string-less steel balls. When I had brought them home, I put them in immediately to test them out. I put one in just a little bit, just a half of a fingers length in, to see how easily I could get it out. I bared down and it came out in a pinch, so I did the same with the second. All was well. I liked the weight and the little box it came with. They can conveniently be stored away anywhere. It even fit neatly in my purse. The box sealed nicely and nothing from my bags could sneak inside of it. At the time I was traveling a lot, so it was great that they could come along with me. They are an easy clean with soap and water.

I wore them for only about 15 minutes at a time for the first few days. I felt that they were only minimally challenging to keep in. Occasionally, one would pop out with a lot of movement, like running up the stairs for example. Aside from that, I could barely feel them.

After about a month of using them, I barely even remembered I put them in. During a busy day, I'd notice the box and think 'oh right, there's balls in me' and pop them out. One day I decided to go shopping at the mall with my significant other. I thought it would be a good idea to put the balls in and hopefully work my kegals for a record three to four hours. Walking around a ton might make me feel them more and put my muscles to work, right? As, soon as I got in the car I forgot they were there and occassionly think about it and flex a few times. So we get home later that evening and I head into my bathroom to take these puppies out and store them away for the night. They did not come out like the normally did from baring down. I stood in my bathroom doing squats, jumping jacks, pull ups and all kinds of crazy activities with my legs in the air. The were not coming out. Finally, I decide to reach up there and I could not feel them at all. I knew they were still up there because I'm sure I would have heard or felt them falling out. In a panic, I run to the living room to my boyfriend for help because I thought they were lost forever. He reached in with his fingers to try and retrieve them to no avail. I had to lay on the couch with my legs up on the armrest while he fished these little guys out of my vagina. The whole ordeal took about 15 minutes. Mind you, the research I had read about kegal balls all said they could not get lost, but NONE said anything about getting stuck.

After a hesitant few weeks, I wanted to give them another chance, so I wrapped them up in a condom, but I just wasn't diggin' it. Now these balls are long gone and have seince been replaced with many other sets.

There is no weight to be found with these balls, and I do not have a scale that would accurately weigh them.
They measure 2.5 inches in circumference and 3/4 inches in diameter. They're extremely easy to clean. Soap and water can be used. I saturate them in my favorite toy cleaner.
As they're made of metal, they're a 9 on the safety scale.

I think these balls were just okay, but after the incident I'd never use the ones without strings again unless they were significantly larger.

I've had these for about 4 years now and I haven't used them in almost that same amount of time. I still might recommend these to someone without a long cervix, but there are far better kegel trainers out there. These are just hanging out on my shelf, never to be used again. If you really want a set without retrieval cords, I'd say that a pair that are larger would be better, maybe the glass ones.
