Improvements Neoprene Tumbler Carrier Sling with Pocket

I was excited to receive this item because by using a coupon was a good price. But now I'm not sure. The item itself it's okay, but the zippers they get stuck and they are not smooth at all. I thought I got a bad one but when I got another one for the exchange, it's about the same. Not buying this brand again. But if you don't mind zippers that aren't did smooth, this one is for you.
