If you are talkin about the one's for like 15 on ebay, then they work great!! I bought one about 6 month's ago off ebay for like 14 with shipping and it's worked GREAT for me. I dont know why you would want to spend the 80 for the name brand. My local head shop had the 2 inch space case for 65 bucks and the one I got from ebay looked identical for 50 less. Just my 2 cents though
