    Will not dissappoint!

    Makes the job so much easier! I wish I had this 25 years earlier. You can hold the barrel of the grease gun with one hand and pump with the other like intended. Grease goes into the fitting every time , no mess. Great Product.

    Third hand

    These will help you more than you'd think. Especially if you use an old lever grease gun. Mine is on a pistol type but it still helps a lot. It really hangs on the zerk well and easily releases. They're worth the money.

    Removes the hassle

    Whoever invented this device deserves a pat on the back, and all good fortunes I hope. The product makes using a grease gun a whole lot easier. Pull the trigger, push it in place, let go of the trigger and pump your grease. Pull the trigger, it lets go. Go to the next fitting, repeat.. For as long as I am going to use a grease gun, I will never be without one of these fittings.

    Works good.

    It works pretty well. Could be a little smaller. It's sometimes hard to get pushed onto the grease fitting but it does stay on and all the grease goes into the part being greased. Wish I would have bought one years ago.

    Time saver

    It makes greasing those hard to reach places. Like idler arms on riding mower decks. So much easier and faster. Just attach it to the zerk. Pump in the grease. Then remove it and move on to the next one. No more having to hold the end of the grease gun. Then watch to make sure it stays on and the grease goes in. This would be an excellent addition to a battery powered or pneumatic grease also.
