Bests & Worsts Reviews from Amazon

Folks, I have had both the 21212 and 21272 trimmers for couple of years. And I have hated both... Both suffer from the same simple problem: neither of them properly release lines. Yes, I have tried to put the .065 lines so many different ways (tighter, loser etc.), but no avail. As a result, my trimming/edging job took 5x times, I had to stop every 10 feet to manually advance the line. And if I got lucky and the line advanced properly then the spool got used up within couple of minutes of edging/trimming. I was about to throw (give) them away, until recently I thought of a hack. I had .105 flexible line for my 10 Amp trimmer (what I use for brush trimming in the back of the property). Here is the Amazon link to it: https://www.amazon.com/dp/B00MD2APKS/_encoding=UTF8?coliid=I1VJGKJ7IL94BT&colid=1U1YPGUS14IF8 I find this particular line more appropriate, it is softer material and it has the triangular shape to it and as a result I get a very thin blade like cutting path. Rigid, round shaped generic lines will produce a wider cutting path because of the inflexible, rigid curved lines. Here are the simple steps I took: 1. Measured and pre cut lines. 2. Took the empty spool out. 3. Threaded the .105 line through the first hole. Note: 21272 needed a little of widening of the holes the 21212 had already wide enough holes. 4. Tied a simple bow/nut on the stem. 5. Threaded the line through the second hole. 6. Evened out the line to make sure it is symmetric and the bow is in the middle 7. Removed (unscrewed) the line cutting blade. There is no need for it on a fixed line and I get another half of inch line length.. 8. Put the cap back Take a look at the pictures. I did a full edging job with both and I cannot be happier. Of course, each line only lasts until you wear it down, but it only took me 1 minute to put in my own pre-cut lines to get going. I created my lines by simply cutting them to the right length. I measured about 10-15 full minute (about 400 feet of edging) continues run before I needed to replace the line (wore it down). Can you imagine your $30-$40 trimmer working with a .105 line? Can you imagine what output, efficiency and trimming/edging speed you get? Simply amazing... The difference in ease, speed and strength of trimming/edging is significant. And there is significantly less line needed. I can see the $12 200 feet .105 line package lasting me for a year, while I needed to buy the .065 packs monthly. These trimmers would have earned a 1 star otherwise, but with this hack I am giving both a 5 star. You cannot beat the ease of use, strength and speed at these price points. Disclaimer: I am sure the manufacturer would advise against this hack, so please use it at your own risk. On that note, I know the manufacturers have to sell ready made spools and lines (they make money on them), which this hack would eliminate both. I still think they should look into providing this as an option, they would make a lot more happy customers. One more thing. The 4 Amp 21212 trimmer is more challenging to do edging with, the wheels on the 5.5 Amp 21272 make my edging job much faster and easier. Both of them do very well for weed eating, it is difficult to notice more power from the 21272, they feel spinning at similar RPMs. With this hack both of these trimmers will do very well for their intended use.
