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. Review: Definitely worth it! - I have an older truck and my riding mower have numerous grease fittings.
