My package was missing a strap, 2 blocks were there, 1 great, the other one clearly used and smelly. I ordered a replacement, the second batch missing a block and strap, and it was too smelly, with lots of bumps showing its use. I am truly unhappy, this is such a great product but delivering used items over and over is frustrating, especially when you pay more.

The blocks are firm & sturdy without being very uncomfortable, and without being more squishy. The strap is also great for more variety of exercises. They are very light weight and such a cute color.
