I was always taught to start with the positive so here we go. These balls are the perfect size to be comfortable and easy to insert with lubricant and take out. However, there are many things that I found to be issues. Although, they are described as smooth there are little divots in both of the balls that act as a spot for "stuff" to collect and this has to be meticulously cleaned or bacteria can grow. The Vibro balls' texture is not stimulating; therefore, I am not sure what the pockets were for. The balls are connected by a string and I am always worried that I have not cleaned it well enough.

Once these balls were inserted, I found it difficult to keep them where they needed to stay to be comfortable. This may be due to their heavier weight. Inside of the balls are smaller balls that move and create the sensation of "vibration". I was never able to get this sensation. First off it took way to much movement for me to even move the inner balls and the only time I really felt it was rocking in a rocking chair. Even while rocking, it felt like they were clunking back and forth. I even used these with other toys and was not internally stimulated while I was contracting.

I have noticed that the gold paint does not peel off and is non-porous. One of the intended uses is for anal stimulation. Personally, I feel that the balls are too large and the string is not long enough. It is already hard to clean and I can only imagine how much more difficult that it would be if it was used anally. The case that the balls come in is not very useful. After using it a few times, the lid finally broke off and it became unusable.

They never got anymore comfortable and always felt ackward. I ended up throwing them away and am now shopping for a better set.
