JCB Grease for me. Makita launched a new 18v grease gun at a trade show about a year ago. I think they might have some in the states now. I’ve communicated with them a few times but no news on release in UK they blamed covid. All my kit is Makita so having the batteries etc already is the incentive of waiting.
I have looked at the Milwaukee a few times but it’s the cost of investing in a new brand. Charger, batteties etc.
The air compressor grease gun I have is good for when at the yard but 20m hose doesn’t quite reach to work offsite
