Additionally, the pre-set grease counter dial allows for precise application, which is particularly useful for tasks requiring accuracy.

However, it is important to note that this model does not include batteries, so they must be purchased separately.

This tool ranks well in its category, making it a dependable choice for both professional and personal use.

However, at 3.64 pounds, it might be a bit heavy for some users, and the manual power source means it requires a bit of muscle to operate. While it doesn’t require batteries, this also means you’ll be doing all the work. Given its strong build and ease of use, it's great for those who need a reliable grease gun for frequent use, but it may be overkill for those who only need it occasionally.
