Has anyone used them and with any sucess? For those of you not familar with them here is what they look like http://cgi.ebay.com/Metal-Halide-Aqu...QQcmdZViewItem
I would like to get some opinions on them before I spend $50 on it. I am in college and as much as I would love to, a chiller just is NOT in the budget. I would like to use ice bottles but no one is home enough to change the bottles. Thanks so much!
