Darwin’s Grip® G7 – Inclined Extension Handle for String Trimmers – Engineered Leverage & Clearance Design – Universal Multi-Tool Attachment

I shouldn't have waited so long to get this attachment. I think it reduces brush cutting effort by 50% by reducing fatigue from constantly balancing shaft distance (weight of the tool) from the cutting surface making each pass a more precision cut. It results in less passes to get a finished result. It won't cut the brush for you but certainly make the job easier. I also liked that the extension handle could be adjusted to many different positions. I'm sure another user wouldn't position the extension exactly like I have positioned mine, so having infinite adjustability is a big plus. If you have a gas power trimmer, you need this.

OVERVIEW: I'm 6'1" tall, and I use a Stihl FS91R trimmer. Prior to purchasing the "Darwin's Grip" handle, I had moved the D-handle all the way up, right next to the strap holder (after I'd cut away and discarded the plastic hand grip thing that came with 91R). Still, I found myself bending over more than I wished. So I went in search of a solution, and I found the "Darwin's Grip." I do a fair bit of string trimming per week: 10+ hours every week on a hilly, rock-strewn property in West Virginia. SUMMARY: after about six hours of mowing with the Darwin's Grip, I find it is definitely what it advertises to be: a way to remain standing more upright as I use the trimmer. It is definitely a positive addition to my FS91R. I rate this a 5-star product. INSTALLATION: not that challenging. I heeded the advice to avoid over-tightening the hex bolts. I snugged them down, but I did not crank hard on the bolts. It wasn't necessary: snugged down is all that's needed to hold the thing in place. POSITIONING: as others have noted, this will take some fiddling with to get it right for your preferences. For example, the pictures showed the handle on top of the trimmer shaft, at the "12 o'clock" position relative to shaft as you hold the trimmer. I found it more comfortable on my left arm (I'm right handed: I trigger with right and use my left on the handle) to rotate the whole assembly to the left so the handle is at about the 10:30 or 11 o'clock position. Just that little bit helped quite a bit. Expect the initial install to be an approximation, with fine-tuning of position to follow. Also, some "muscle memory" my need to be re-learned to use the new handle naturally. For me that took about an hour. QUALITY/WEIGHT: the whole assembly is very light weight, and I don't notice any difference with my FS91R (14lb machine) with this installed. It seems fairly sturdy, but I would not jerk on the handle, nor push down on it hard. With just normal pressures to control the trimmer this should be just fine. As others have noted, the weak spot in this is the toothed-swivel that allows adjustment of the handle up/down from the trimmer shaft. Again, normal pressures and it'll be fine; aggressive jerking, or pushing down hard would be a problem. VALUE FOR MONEY: the item is $70+ with tax, and at first blush that seems high. But in my early testing of this I've discovered two things: (1) my back is no longer fatigued; and (2) because my back is no longer fatigued, I take fewer pauses, which means my mowing gets done more quickly. Preliminary estimates has the time savings in the 20% to 30% range. So, for me, the $70+ expenses is forgotten, and now I'm enjoying the benefits.

Game changer, I'm 6"3 and I no longer have to bend over to use my Ego power shovel. Worth Every Peny! Fully adjustable for all body types.

Only providing 4 stars at this time, because I have not found the "sweet spot" location on my weedeater. I have used and the results were good, but I am still adjusting the location on my Echo. The grip was easy to install and I believe it will help reduce back fatigue.

Yessss , my back is saved!! Easy install, easy to use, comfortable

Absolute necessity - watch your torque and consider using thread locker. A back saver for sure! Would love to buy some more of the trimmer line that came with the handle - that stuff is great - but had no name on it.

Back saver! Love trimming but so hard on my back. A physical therapist suggested this to my daughter and let me tell you, it’s so helpful! You’re not bending or reaching with it. Take a little adjusting to your personal need, but it’s worth every penny!

So this attachment works for some scenarios and other scenarios not so much if you're weed eating a ditch and or steep bank you're not going to want to use this it's too high and awkward it's the best way I can explain it if you're just weed eating like normal on flatish ground it's perfect I'm 6 ft tall 200 lb and I do landscaping professionally it really is a big help less straight on your back there is a learning curve because for some reason you still want to hold the weed eater higher than what you need to cuz it needs you to relax the arm of which you're actually using to throttle the trigger with is it worth the price honestly no they should really calm down from this price I would say catch it on sale if you can catch it on sale for around 30 bucks 40 at the max it's a really good deal I would almost say a must buy but at 60 bucks no build quality is good it's metal construction with only a few plastic components The rubber handle keeps wanting to slide off it's not hard to put it back on there The design it's okay The weight it does make your weeder heavier a kind of also throws off the balance
