I know that the 18" Tiger Tail is shown here, but I wanted to let everyone know my thoughts on a very similar product by the same company - the 22" Tiger Tail. My 22" Tiger Tail is so not worth the $30 I paid for it. I could've made this at age 10. How do I know? I know because it fell apart on me on the first day - not because it broke, but just because of poor construction and assembly.
When I was gently moving the roller around in the middle to examine it, I noticed that the edge of it (barely protruding from the black foam) had some familiar looking markings; it looked like a PVC pipe that had been sawed and not sanded down to be smooth. The handle accidentally popped off and went tumbling across the floor, and that's when I realized how cheap and overpriced this product is.
Why did it look like PVC pipe? Because it actually is! The handles are simply pushed onto a 1/2" diam. PVC pipe (mine actually still had the crude markings, size, company, etc. that you see on PVC pipe you obtain from hardware stores). They could at least secure the handles on there! The black foam is fitted onto another PVC pipe (I think it's 3/4" diam) and slid over the longer 1/2" pipe. The inside of the 3/4" pipe and the outside of the 1/2" pipe are "lubricated" with a light grease - I'd say something a little lighter than petroleum jelly (Vaseline). Throw together some PVC pipe + foam + handles + cheap grease, and Voila, you have yourself a Tiger Tail.
You can get it to work and do the job, but probably not as well as you should for the price. Here are my complaints. 1.) Sand/polish ends - They could at least polish the ends of the PVC pipe that were cut. 2.) Secure handles - How hard is it to secure to handles that slide onto a PVC pipe? Using glue or an adhesive is not rocket science. 3.) Make rolling smooth - One big thing is the lack of polishing between the pipes. They should make surfaces between the 2 pipes (the ones that actually rub together as you roll the TT over your muscles) smooth so that the rolling feels frictionless. When you press harder to get deeper into the muscles, you feel that the PVC pipes against each other are not smooth. Maybe they should just use better materials. 4.) Grease? Come on now. That will attract dirt in the long run or eventually dry up and your TT will be even less smooth when rolling.
Bottom line: Cheap parts, cheap construction, way over-priced. The Stick is much better quality (just hope you don't get one with foul-smelling rubber handles like my Sprinter Stick has).
