Could not get the threads to work on my weed eater. I had to rethread the bolt then made it work. Can't tell how long it will last

Works well but no directions
Would RecommendThis works well for the Kobalt 80V string trimmer. I am deducting a star because there are NO instructions. Go on youtube and you can find out how to remove the old trimmer head (you need a hex key tool). Also, for some reasons this trimmer contains two separate pieces of string, which stops working as you wear it down. You have to remove one of them...this trimmer works only when loaded with a single piece of string.

Would Not RecommendApparently, you ha no parts for this weed eater. Really, really BAD

Kobalt V80
Would Not RecommendI have used my Kobalt v80 very little and now need a replacement head and cannot find a replacement head from any one else because when mine was assembled the threads were striped. And now Kobalt doesn't make any more of these... The trimmer works good, but the head has always been junk.

Does not fit
Would Not RecommendWhile I enjoyed the 80v max trimmer because I can hear my kids while I’m in the yard, I’ll be going back to stihl. It took for ever to find a replacement head, which ic close to the original, but not the same. To me that shouldn’t be labeled as a “direct replacement” for the 80v max. Finally got it in just to find out it doesn’t fit. It will work if you trim ⅛ inch off the spacer under the spool, then press the nut out of the old spool, and press it into the new one. Should’ve been a 20 minute j...

can't find replacement spools for 40 volt trimmer
Would Recommendwhy does the lowes web site show they have kobalt replacement spools but when you go they say they have never carried them. i have wasted my time on 2 trips to lowes dickson, and on internet trying to find. i bought my trimmer in march of 2021 and love the trimmer but you would think the spool and bump knob would last longer. will now have to pay shipping from other lowes location.

Don't get a Kobalt

style of trimmer head does not have replacement spools, you would be looking at a head replacement. The trimmer head on this unit is made for easy replacement of the string on the spool. This string trimmer is designed with an easy-to-re-spool trimmer head. There are two methods in which the trimmer line can be replaced. You will need approximately 15' of trimmer line at .080" inches in diameter. For the first method: Note the hash mark on the knob and the hash mark on the spool cover, while holding the spool cover in place with one hand, turn the knob until the hash mark line up with the hash mark on the spool cover. Then take the trimmer line and feed it through one of the holes in the side of the head until there is an even amount on both sides. Then wind the line into the spool by turning the knob clockwise. If you wish to readjust the line or if the line has been wound too short, push down on the knob and wind it counterclockwise. Be sure to leave about 5 inches of slack on each side of the spool. Second method: Remove the spool cover by simultaneously pushing the two tabs located on side of the spool cover. The cover should spring off, lift the spool out and feed the line through the hole in the center of the spool until you get an even amount of line on each side. Put the spool back in the trimmer head, making sure that both sides of the line go back into the grooves in the trimmer head, continue to hold the spool in place. Take the spool cover and put it back onto the trimmer, using both hands press down firmly to ensure that the taps lock into place, you can now rotate the knob on the spool clockwise to rewind the line back in making sure to leave the 5 inches of line on each side of the spool. For further details or for further instructions on replacing the string onto the spool, please feel free to contact our helpline at 1-888-3KOBALT (1-888-356-2258). />
No Instructions
Would Not RecommendHow am I supposed to install this? It does not come with any instructions. I may be stupid, but it is not intuitive as to how to get the old one off to install the new one.

80V Trimmer Spool
Would Not RecommendVery pricey for plastic. Design was slightly different than original, therefore I had to use a combination of old and new parts. Wish I could have bought only the part that you tap to feed trimmer line. This comes as an assembled unit, it would be more convenient if components were sold separately and making replacement less expensive. I couldn't find Kobalt parts elsewhere so they have you over a barrel after purchasing an expensive trimmer.

Not sure what the fuss is about...
Would RecommendYeah, my store didn't have in stock, so I ordered it online. It took ONE week to arrive - big whoop. One spool lasts me two years, so this isn't a huge expense. Trimmer back in business!
Concerned about other reviews, happy with result
Would RecommendAfter reading the other reviews, I was concerned that this would not fit my 80v trimmer. It seems that the thread changed at some point causing a fitment issue for others. I went to the local store last night to get the Shakespeare head that can be adapted to any trimmer and found this on the shelf as a cancelled online order. I figured I would give this a shot because OEM direct fit would be easier in the long run. Sure enough, it fit. I purchased my 80v trimmer (623439) back in May 2016, ...
Kobalt 80-volt trimmer
Would Not RecommendOriginal replacement spool released “string” too quickly. For that reason, I purchased this replacement spool. Some usage is required before I know if problem was a one-off issue because in general the string feeder on this 80-volt Kobalt trimmer is definitely an upgrade from The 40-volt Kobalt trimmer. Battery charging is good as most rechargeable are quite good today. The quality of the actual string used in the 80-volt is also exceptional.

Perfect Fit!
Would RecommendThis replacement head was exactly what I needed and fit perfectly. The only issue I had was that there were not any instructions on how to replacement it. After a couple failed attempts, I finally Googled it and found some fantastic help from a guy who had the same issues as me. My suggestions...some simple instructions would save your customer a lot of frustration.
