So much for your money! A truly comprehensive set!
Tons of variety and combination
Easy to insert and remove
Wish there were better color options (me just being not picky)
I thought the anchor point in the middle would be stiff; it's not, it's very flexible and has a lot of give.
They're very beginner-friendly, and I'd say the only set you'll ever need unless you want to go really heavy or non-silicone. I wanted a very comprehensive set, one I could buy and probably never need to look at other sets again (though I do want a vibe one). The balls have the weights on them to! So you'll never get them mixed up. (Like pussy dumbells)
The weights break down is as follows
100g (30 30 &40)
110 (40 40 & 30)
And if you're crazy and want A LOT of weight, you can use all 4 of course.
Now, the vibes. To start out, I used one single 30 with its holder, and I can honestly say at first I didn't notice, I took a shower, did the dishes. Then I sat down and started squeezing, just to see if I could feel anything. The ball moved (I'm in my late 20s, no kids) up, and when I stood after doing 30 Kegels, I felt it vibrating way up there somewhere when I started to walk out of my living room. I tried the other 30 with it on the double holder, and I was impressed! I thought the vibes wouldn't be that strong, but I could definitely feel them! Expectations exceeded!
The size is good; the larger balls are about 1 3/8th, so a little under half by my caliber. The small ones are 1 1/4th. Not much of a size difference. But from my research it's not about size, it's about weight. The bigger they are, the easier to hold anyway, but it's a work out it's not supposed to be easy.
Oh, and they are making me wet, so there's that.
