Works as it should

seems to be well made, but have not tried it on the weed whip yet.update, my trimmer has never advanced line so reliable! I highly recommend this product!

Product as described

The bump head knob was exactly like the old one, however the bolt wouldn’t screw in to fasten the knob to the head. The thread pattern on the bolt looked like the thread pattern on the trimmer head, but Im assuming it was the opposite thread pattern. I ended up removing the bolt from the new head, then taking the bolt from the old, damaged bump knob, and put it into the new knob....bingo, it threaded just as it was supposed to. I guess I shouldn’t lose the old bolt, as I’ll need it for the second knob.

I ordered a two pack from Amazon. The items got here in two days and fit perfectly. Cheap price and works great.

Did not fit my TroyBilt correctly

starting a mower shop and will need parts like this often

Ordered this as a replacement, so far it's doing okay.
