For about 3 years throughout the year, it used to be a scooter for commuting as well as sunny weather or rainy weather.
Three years later, the epidermis cracked, and the gel inside protruded out in a trace amount. But let's keep it good as it was kept just this.
I did not do any oil maintenance of the epidermis, so maybe I lived a little longer if I treated it.
Because the tire of the second-hand purchase scooter was hardened old, the ride became bad (anyway the ruggedness and repulsion comes directly), so my butt hurts. Pain relieves when wearing this product. After that I replaced the tires with new ones, so I feel little pain. However, if you run for a long time or a long distance, I will be wearing this product because it hurts so much. If you have one, you can use scooter or motorcycle and change it convenient!
