I purchased this to replace my damaged head on my Stihl trimmer. Removing the old one and replacing with the new one was beyond easy and probably took a total of 3 minutes. Opening the unit up to refill trimmer was a bit stiff but opened up with a little extra pressure with a screw driver. I suspect over time this will loosen up as did the original equipment. Overall pleased with the replacement product and was pleased with the reasonable price.

Works just as good as the OEM at a fraction of the cost. The only slight difference, which doesn’t affect fit, is the bump part sticks out a little further than the OEM, or my OEM original was just that far worn down.Installation is easy, there’s a small hole in the trimmers head (may be hidden and plugged with dirt and grass as in my picture), stick a small screwdriver in that hole, rotate the head by hand until you feel your screw driver catch. Unscrew the plastic head by hand, NOTE: It’s a “reverse thread”, meaning you turn it counter clockwise to loosen, clockwise to tighten. Hand tight is all you need, it tightens itself from the direction of its rotation.There’s a bolt head on the opposite side of the hole, its there so you can shoot some grease into the head. If you’re having to replace the part being reviewed its probably already past time to put some trimmer head grease in there.The couple reviews I read of people complaining this replacement “sticks” need to use a little common sense. The OEM ones could stick sometimes as well, the solution is simple. When you take it apart to wrap more string clean the dirt out of it for one thing. You can also take sand paper and smooth out around the bump mechanism and the inside of the hole on the outer cover, common sense, until it works smooth and freely.

Works pretty good. Comes loaded with string. Good price for two spools.

Works as advertised, great fit, great part.

fit great work very well on MY FS 70RC

I purchased this to replace the bump head on a Stihl trimmer. Very easy to install and appeared to be a good quality. The line feeder part, however, does not work at all. It will not feed out the line and so the line just breaks at the head. I have spent more time stopping and taking the head apart just to get the line to feed out when bumped. I purchased additional bump head line feeders from a different company so I am hopeful that I can use them to replace the line holder/feeder on this one.

Saved money buying this replacement bump feed ,I use it on my Stihl FS 56RC works great.

Ordered this for a Stihl FS55 trimmer. Fits perfectly and seems to be made very well. The bump works great. As mentioned it comes spooled with a small amount of trimmer line. I wasnt expecting it to come with any so that was a bonus.

Trimmer head fits perfectly, operates just like original

Works great

Connected fast and easy. Works really well. Very happy with my purchase

Product just as reviewers described.
