Review on EOCICI Grease Coupler Release Fittings by Pogo Shakey

I bought this Lubricating Coupler and Locking and Lubricating Coupler. I have several grease guns so I decided to buy both. I actually prefer this one because it has handles on either side to compress the stiff spring to tighten the zerk. This makes it much easier to squeeze to open your mouth. Both units appear to be of the same quality but the lock and lube comes with a full rebuild kit while this one only comes with an additional internal rubber seal. I'll probably lose both before they have to be replaced. These clutches are for my personal farm use only, so I won't be using them every day. I assume (for now) that both will last as long as the grease guns in my application. The lock and lube are physically shorter by almost an inch and this can allow it to gain a foothold for jobs in tighter spaces, but I've bought a couple of 90s for those situations as well. I'm keeping both, but I think this is the best "value".
