The best use for the Pleasure Ball that I found was during foreplay, for massage. It's an odd shape, so it didn't fit between my legs well, and can't be used for pinpoint stimulation. It is fun to roll along either your own or your partner's body to stimulate either before or during sex. It can be used to stimulate the external areas of the vagina, but I didn't find it all that arousing because I just couldn't get it into a comfortable spot.

It does work really well for a neck massager when you are on your own.

The Pleasure Ball is made of plastic and TPR. I have the purple/lavender one, and the darker purple side is hard, shiny plastic while the lavender side is made of thermoplastic rubber. The plastic side is slicker, and if it gets wet at all it is slippery and hard to hold on to, luckily the TPR side is easy to keep in your hand, and keeps it from sliding around when you don't want it to. Because the ball is waterproof, the TPR side comes in handy for water play.

I personally preferred the TPR side against my skin, but that sometimes caused issues if I was trying to hold it with the plastic side. It tended to be a little slick, especially with any sort of lubricant. Also, the vibrations are based in the plastic side, so that is a downfall.
Luckily TPR is hypoallergenic and phthalates-free, so there aren't many worries with it, just make sure you keep it clean.

I have a love hate relationship with the Pleasure Ball. I love it for massage, I hate it for trying to achieve an orgasm. Because it is so large it just was not comfortable in most positions. I have tried sitting on it, laying on it facedown, laying on my back with the ball between my legs, and reclining with it between my legs, it just wasn't all that great for me. I never got close to orgasm at all.

I do like the "nipple" shaped on/off button. The same button also controls speed, and there are 3 speeds.

According to my measurements, the ball is 10 and 1/4 inches in circumference, 3 1/4 inches in diameter.

To get to the batteries you untwist the halves of the ball in opposite directions. It uses 3 AA batteries. There is a thin rubber seal around the edge of the TPR half that makes this ball waterproof.

The Pleasure ball seems fairly well made, and is fairly heavy, though not overly so.

The Pleasure ball doesn't LOOK like a sex toy, so it is fairly easy to conceal, but I wouldn't recommend it for travel as it is fairly loud, and seems to get louder the longer you use it.

The Pleasure Ball is very easy to use, it has 3 speeds, low, medium and high. The vibrations are centered in the end of the dark purple side (in the purple version), this is the plastic side, not the TPR side. I wish that the sides would have been reversed, but I imagine it is because of the waterproofing that the tpr side has the control button.

The ball is very noisy. It started out fairly quiet...but everytime I use it it gets louder and LoUdeR and LOUDER. Now it is loud enough that you can hear it from another room, sometimes with the television on!

Using the ball in water caused no additional issues. Afterward, I checked the battery compartment and found no water. I did find it to be slippery in the water, and if it touches the bottom of the tub or sides, the noise is deafening. For some reason, it tends to have stronger vibrations in water. On dry land I seemed to keep the ball on either medium or high, in the water low to medium.

The Pleasure Ball is easy to clean, being plastic and TPR, you can use soap and hot water, or antibacterial toy cleaners. I found no problems cleaning it. Since it is waterproof its pretty easy to clean since you can immerse it. I do open up the ball and clean around the edge where the two sides come together each time I use it though. You cannot boil or heat up this toy to clean it. It will melt.

TPR can be used with silicone or water-based lubricants with no interactions. I keep this toy stored in a velvet bag in our "fun chest" but since it doesn't react to anything you don't have to keep it separate from anything.

The ball is packaged in a flimsy plastic box. There were basic instructions included, but the ball itself is pretty self explanatory. Twist the ball to put in batteries, click the button once to turn it on, continue clicking to change speeds, on the 4th click the ball will shut off. The package is not very nice looking, so I would not use this as a storage or gift box.

When using the ball I tried using it in many positions, in many situations. I could get stimulated using the ball, but never got anywhere NEAR orgasm with it. I do love the ball for massage and foreplay though. Both my husband and I love rolling it around on each other's bodies and stimulating each other. It makes for a fun night.
