Review on Carbyne Professional Anodized Aluminum Extension by Dan Bobbert

Pretty good grease gun. The supplied hose is too short. An additional longer hose should be supplied with the gun but must be purchased separately. The seal on the piston inside the cylinder is not replaceable. This seal usually wears out over time, leading to gun failure. The floating spring on the hose is not good. It is needed so that the hose does not twist. If necessary, the spring should be attached directly to the coupling on the hose to prevent the hose from kinking. A rubber boot to act as a grip for the barrel is a good idea, but the rubber wears out quickly. The handle should be neoprene to last longer in the lube. The grease gun looks good but could use some improvement. Made in China. One more thing. The oil bowl comes with a note card stating that the buyer should not return this Revain product if you do not like it as it will cost too much money to return. If you make a good product that works as described, you don't have to return it.
