Carbyne Grease Gun, Pistol Grip, 7500 PSI, Heavy-Duty Professional Series

Upon arrival I loaded it with a tube of Dexter Lithium #2 grease. After a short period of time I noticed grease leaking from the bleed valve. I reset the valve several time in hopes of correcting the leak to no avail. I then sent an email to seller customer service and immediately heard back from a rep named Jacob. He advised he would immediately send me a bleed valve and for my troubles a gun kit, what ever that is. I was very appreciative and delayed finishing the job I started assuming I would soon receive the new bleed valve and and took the pressure off the grease gun to slow the leak. I am located in Las Vegas and the valve was being sent from CA. I waited for over a week and emailed Jacob and never heard back. At this point I will be returning grease gun to Amazon. Very disappointment and never again will I purchase their product again. I understand things can fail but when new I expect support and not phony lies. UPDATE: Prior to returning the gun to Amazon I again contacted the mfg in regard to not receiving replacement bleed valve as promised. I was advised it had been sent but they would resent one immediately. They were very apologetic and understanding. Within a few days I did receive a new valve as well as a bulk loader. I replaced the bleed valve and the gun works perfect, no more leaks. The only question/concern I have is the strength of the spring. I have never used a grease gun with a spring so powerful. Bottom line, the gun works as designed w/o leaking and I had great customer service. Hence the 5 star rating.

This is the finest grease gun I have ever used let alone owned and I've owned several over the years - each one has been a nightmare to use. You know the story, grease everywhere but where you're intending and erupting from every connection point on the tool, right? Well, I own a lot of tools and rarely get excited about any of them. I have to admit that this tool worked so well it prompted me to throw my not-so-old grease guns (two...) right in the trash and bend my wife's ear about what a great tool this was. I did take the advice of another reviewer and installed Teflon tape on all of the threaded connection points prior to use. I can't say whether or not this was necessary, but it seemed a small investment in time to avoid those annoying grease escapes.

Feels sturdy in craft and ergonomic in design. It's nice to have a handle that's on the side, that doesn't use the cylinder as part of the lever system. The hose and fitting feel like they're quality made and the gun works well. Also, having the end cap is nice for cleanly storing the gun. I love being able to grade the chassis myself now, and it's very easy to do on your own. Definitely get the grease that has a can opener at the top—makes canister instal easy and not messy.

Alright so to start, it looks and feels high quality and it does its job just fine. The only problem I had is if you let it sit for too long it does leak. To be fair, I expected as much, but for the price I kind of hoped I wouldn't see any leaks. Still a great feeling grease gun and serves it's purpose.

Having owned another gun before that was nothing but trouble, I appreciate the Carbyne unit working as it should. It comes with great instructions and has been problem-free in running two tubes of grease through it. No leaks, good ergonomics, no priming problems. This is a high-quality gun that's well made, actually looks really nice, and works! I'm very pleased with my purchase.

Fast shipping, solid great looking product. It comes with a straight stainless steel 6" fitting and a flexible hose fitting. It fit the standard 14oz grease insert perfectly. I greased some CV joints (with a separate grease needle) and upper ball joints with no problems. This thing looks to be build to last a few generations.

Fairly good grease gun. The hose included is way too short. There is an optional longer hose that should come with the gun, but you have to purchase that separately. The seal on the plunger inside the barrell is not replaceable. This seal is usually what gets worn out after a period of time and causes the gun to fail. The floating spring that is located on the hose is worthless. It is there to prevent the hose from kinking. The spring needs to be attached to the coupling on the hose directly, if it is to keep the hose from kinking. The rubber boot that acts as a gripper on the barrell, is a good idea, but rubber will deterioate in a short period of time. The gripper should be neoprene, that will last longer around grease. The grease gun looks nice, but there is room for improvement. Made in China. One more thing. There is a note card that comes with the grease gun that indicates that the Buyer should not return this product to Amazon if you don't like it, because it cost too much money to return it. If you make a good product, that functions as described, then there is no need to return it.

This is the best grease gun I've ever owned. It is very well thought out and has many nice features that make it a joy to use. First of all, it's very clean and doesn't leak grease all over everything. Just make sure you tighten up all the fittings before using it as they are loose so you can use either rigid or flexible attachments. I love the firm grip coated pistol grip handles and the rubber coated container tube which is about half the weight of the barrel on my other gun. There is a finger operated spring loaded air bleeder on the head assembly, but if you follow the well written instructions I doubt you'll use it a whole lot. Speaking of which, the instructions are excellent, written 100% in English, and are very easy to follow. This gun was very well protected for shipping, double boxed by the manufacturer then boxed up again at Amazon.com. I am VERY pleased with this purchase and just hope that it stands up to repeated use over the next few years ~ time will tell, but for now, it's a real joy to use!
