We love the BB 8, we think it is a great device. But with that said the price tag of 150$ is a bit too high to justify a purchase, unless you are a BIG Star Wars fan like us. With that said it is a fun little gadget and operates well on most surfaces. Even, most rugs BB 8 can perform on. With that said if you own a heavy rug, this is a pass. Poli Games gives this product a soild B+. The force is strong in this droid. You can check these pictures of this cute little droid.
Here's a picture to give you the actual size of BB-8. We didn't have a baseball on us...because, we're nerds. So i hope everyone knows the size of toilet tissue!
