Based on my experience, this grease gun is an excellent addition to any industrial worker`s toolkit. The battery-powered design makes it easy to use and reduces hand fatigue. The 2.0Ah lithium-ion battery provides long-lasting power and the grease flow rate is smooth and consistent. The only downside is that the kit does not come with a carrying case, but that's a small price to pay for an exceptional tool... overall I highly recommend this product to anyone in the industrial and scientific field..
