Concerned about its lifespan [SEP] It works very well! It blends well, easy to wipe product off of it, saves LOTS OF PRODUCT.  My only concern is that it feels like it will break easily.  I'm not sure if that is just me but I feel like I have to be careful when I use it and I feel like if I drag it the outer wrap of it will stretch out and then it will look wrinkly.
