Review on Speed Feed 450 Trimmer Head By Stens - Faster And More Efficient Trimming by Anthony Tegan

This fit my Milwaukee M18 Fuel Quik-Lok with the pre-installed nut. I only needed the black spacer as shown.Installation was as easy as you might expect, I dropped an allen wrench in the hole, turned the old Milwaukee speed feed head until it caught, then loosened by hand. I put the black spacer on and put the new head on. Tightened it up by hand again and I was done. While I was there I flipped the orientation of the string cutter on the Milwaukee's guard to give me another 1"+ of string stickout.As for performance, I've only cut for about half an hour on this head, but it appears to be working quite well. It could be placebo, but it really feels like it's cutting and feeding better than with the stock speed feed head which is a lot smaller. I assume this could be due to more mass. This would likely also mean somewhat quicker battery drain, but I didn't notice a difference yet.I'll post an update after a while if I don't believe this is still five stars. But so far, I'm glad I made the purchase.
