I just received a ProTank and it works good. It came with a rubber cap on the drip tip which I thought was cool so I could cap it at work when not using. However, when I got to work and pulled off the rubber cap the whole drip tip came off, separated from the glass tank. (this was going to be my second use of the ProTank). All the juice went all over my clothes. There is no way to get the drip tip to attach back on the glass. One would think that the glass tank would have been made with threads on it so the drip tip could go back on. Does or has anyone else had this problem. I've sent an email to the company I bought this from hoping they will allow me to send it back for a new one. I think this one was defective. Any ideas??
