Review title is Great mini-size. Grit doesn't last long [SEP] Pros:<br />Great size, perfect for my desk and bedstand and car, etc.<br /><br />Eh:<br />The patterns are "eh," some suck and some are decent.<br /><br />Cons:<br />The grit wears out very quickly. Faster than a regular cardboard/foam emery board. That sucks. I was hoping that the glass version was an option that would be more durable and last longer. But, sadly, it is not. I'd say within a week, I had worn both sides down on at least 3 of these, so it is now just smooth glass in those spots ....<br />I was willing to make an investment on something that was longer lasting and potentially more eco-friendly (than buying the cardboard/foam ones all the time), but I will have to go back to the cardboard/foam ones until I find something more durable.<br />There is no way that throwing away that much glass every 2 weeks is better than using cardboard/foam. ....
