Good and durable tires that do not stretch, with immediate rebound. I consider them equal to much more expensive brands in terms of durability; personally, they lasted me four years with daily use

They may not satisfy, maybe it's worth spending a little more for at least half of them and have a satisfactory period of time with them.
What I received has no elasticity at all, only for small children, if they fit.

You can do everything with these bands... and with different resistance depending on the user's needs... They are very lightweight, practical case and you can take them everywhere with you. The only thing left is to see how long they will last but for the money, if they can withstand 2 months, I will be satisfied.
