    • Wow, this thing is awesome
    • This thing makes job so easy that I actually enjoyed using the grease gun lolBuy it once and never get frustrated again.
    • This thing is great.
    • Best thing I have ever used with a grease gun
    • This thing is amazing
    • This thing is great
    • One of best things I have purchased for greasing equipment, when you grease dozers, excavators, and earthmovers the simplicity of your greaser just locking into place adds up
    • Installed it on a cheapo auto parts store grease gun, now the thing is awesome
    • Best thing I’ve ever bought
    • I grease a skid steer and mini-excavator almost every day, this thing works great.
    • This makes greasing equipment a breeze, what i like most about the locknlube is it comes off as easy as it goes on, the standard push lock connection on the grease gun went on fine, but getting the damned thing to release was BS!
    • Nothing but good things to say.......works perfectly as described and even includes a rebuild kit for future use
    • This thing is great!
    • Works very well the only thing I wish is that it was smaller and that it had a 90° attachment
    • Best thing since the cordless grease gun
    • The thing just works
    • This thing really does work
    • The LockNLube coupler is the best thing to ever happen to a grease gun...ever!
    • This thing is great, I bought it for my Milwaukee 2646-20 grease gun and their is no fighting to keep this on the zerk, I greased the landing gear on my trailer which hasn't been done in quite a while
    • Best thing you can get for your grease gun.
    • This thing is awesome
    • so i'll give it a try(i've tried worse things)
    • This thing is a guaranteed no brainer purchase.
    • This thing grabs on like a teenager who just saw his first Teton!
    • This thing is a life saver!
    • This thing works!
    • Best thing I have bought in a while, well worth every penny!
    • Best thing I have bought in a while, well worth every penny!
    • It’s the best thing that ever happened to a Grease Gun!
    • This thing is awesome and much easier to attach and remove from the grease zircs than what comes on the grease gun from the factory
    • I love this thing
    • The coupler easily locks on to the zerk fitting, doesn’t leak grease around it, and the most important thing of all
    • best thing since sliced bread
    • The important thing is to make sure that it is seated correctly for greasing (or else it will leak at the tip)
    • the thing works
    • I thought it was rather pricey, but I love the thing an see why
    • n’t think it would work as good as advertised but it works
    • n’t rip off my zerks
