What type of semen tank do you have and do you like it? I never thought that there was a difference in tanks. We had an MVE and thought we needed to upgrade. Well apparently I didn't do my homework. I buy most of my semen from one particular (popular) distributor, so of course I ordered a tank from them and I hate it. I have to refrain from saying a lit of bad words everytime I use it. Once you get s canister out you can NOT get it to go back no matter how you try and it's quite a frustrating process. The new tank is a Worthington 13 out of 10 do NOT recommend. Anyone else have this problem? Im going to refill my old tank and sell this new one.
