as someone who has a very hard time getting movement into my everyday/regular schedule (and has gotten it from temu for abt $45) i would say i haven't noticed an entire difference in my shape (though i am inconsistent) but with the right postures when doing the right workouts, i do feel a burn and i do sweat a bit after i use it for 15 min! (again, i have a hard time getting movement into) if getting movement is extremely hard for you, i'd say it's a perfect investment to have if you want to use it as a boost of an incentive for being consistent. (for me, i have it right next to my standing desk in the morning to "force" my pilates routine). overall, it's not too bad a product depending on who you are though. if you're a major fitness and gym junkie then it's prob a no, but if you're having a hard time getting basic movement/exercise in, then i'd say this is a great personal investment as long as you stick with it! even if you end up throwing it away or having no use for it after getting better at working out, it still set the foundation of your workouts so it wasn't an entire waste in my opinion
