I am 30 now and my tolerance for toys that break in 2 minutes is basically zero. I picked this up during a weekend DIY project when I was fixing the deck and needed something to keep the dog occupied. The E TPU material is straight up impressiveuch abuse it can take from a large breed. My dog tends to destroy generic store brand balls but this one survived being dropped down the stairs and tossed against the siding. It is comfortable enough to use daily without feeling like it is going to shatter or hurt the dog. The internal compartment where you charge it is smart and those little pockets for the charging port are actually useful sized for my fat fingers. The smart movement is a game changer for keeping a high energy dog moving when I am busy with home improvement tasks. I was slightly worried about the 8 hour battery life but it holds a charge well enough for a few play sessions. My whole household uses this now to entertain the dog as he will not leave us alone otherwise. It works best on my kitchen tiles but it barely moves on the thick rug in the living room which is frustrating. The vibration is loud enough to be annoying when I am trying to focus on work. It is a solid 3 star product as it does what it says but has some quirks that make it less than perfect. Spending 19.99 is fair for the durability you get compared to cheaper options. I like that it is USB rechargeable instead of eating through batteries. It is not perfect but it serves a purpose in my chaotic house.
