No longer need both hands to grease equipment and vehicles. Yes it's a little pricey but well worth every penny. Very good quality and well built. Let me start by saying I hate grease guns, always have. The old hand pump ones that you put the tube in, really piss me off. Once you put it on the Zirk, it is such a PITA to get off. This handy little item makes greasing things so much easier. I would recommend this to anyone that finds greasing things unfun when you're trying to get the job done and you can't get the job done easily with the old-style grease guns. ### ⭐⭐⭐⭐⭐ Definitely worth it! *by on Reviewed in India 8 September 2023* I have an older truck and my riding mower have numerous grease fittings. Previously when using my grease gun half of the grease would go in the fitting and the other half go all over the place. With this locking fitting all of the grease goes inside instead of outside! I highly recommend this!! ### ⭐⭐⭐⭐⭐ Nice product *by on Reviewed in India 17 June 2023* I do nice work with this product.And easy greesing to all nippel at anywhere... ## Frequently Bought Together - STHIRA® Grease Gun Coupler, Strong Lock Release Grease Coupler with 12" Spring Flex Hose, 12000 PSI Quick Release Metal Grease Gun Couplers Compatible with All Grease Guns 1/8" NPT Grease Gun Fitting - JCB Tools Heavy Duty Lever Grease Gun with Aluminum Die cast head.
