Amazon Brand - Denali by SKIL 20V Brushless 13-Inch String Trimmer Kit, Includes 4.0Ah Battery & Charger, Blue

DENALI Brushless 20 V 13-inch String Trimmer w/4.0Ah Battery and ChargerI’ve been looking for Lithium powered lawn equipment for some time and never came upon the right balance of quality, performance, and price until now and this was with some reservation about buying an Amazon sponsored brand.Use: For general use around the home and property and gardensNeed: Something light weight, well made, low to medium power, reliable and strong battery, and easy to maneuver for my wife of 5’2”I had four (4) incentives:1) Black Friday savings. At retail I would still consider it a top contender.2) Amazon Denali is a rebranded SKIL product with a 20-volt 4-amp battery rather than a 20-volt lower amp that came with the SKIL version. I’ve owned excellent SKIL power tools in the past.3) The 20-volt power is a good compromise between the lower voltage (under powered) and higher voltage (overpowered for general purpose yard and garden work, heavier, more costly) and the 4-amp rating is excellent compared with the 2 and 3-amp you often see.4) “Bump” Trimming Head. Learn to use a bump trimming head and proper winding of the trimer string. Don’t buy trimmers with proprietary swiveled cutters and other cutting style “things” that break off when you hit an object. Tips flying is hazardous. They become expensive to replace and later unavailable.One (1) Assembly ModificationI made one modification when assembling the trimmer “hinge”. I’m used to high quality metal framed prosumer lawn equipment where a jointed shaft would be disastrous, so I very cautious fastening the screws into the nylon (? It is very well made) “hinge”.Attached find an image showing my minor “hinge” modification in order not to over tighten and deform the hinge housing and risk failure.I added 2 M3 washers (red circle) on either side before tightening the retaining screws so as to prevent any gap between the top and bottom of the housing. You can tell (feel) when using a hand screwdriver (do not use a power driver) when the torque is just right otherwise tightening the 2 halves together would risk failure at the joint.You will see that this essentially matches the “spacer” on the opposite end (bottom) of the hinge. It would have been ideal if they included spacers, but best not to leave a gap between the two.Performance & HandlingIt was great. Much more performance than I expected. While I did not sense any variable trigger speed control (the trigger has to be depressed fully to prevent the safety “off” switch triggering), it does have a low and high-power switch. I found both power levels and speed ideal for trimming around the house, retaining walls, fences, along garden edging, etc. without destroying things. I was surprised that it did a perfect job clearing the roots from overgrown sod on our paths walking stones making the task easy. This would be a heavier workload.A mix of generic, moderate, and heavier cutting got me about 30 minutes at half battery power indicators. Very nice performance. Its always nice to have a second battery, but you should be fine with just one for a modest sized suburban lot.PrecautionsALWAYS wear EYE PROTECTION, long sleeves and long pants. If your cutting “off angle” the trimmer guard will not protect you from flying debris. Example if you’re tilting the string for edging or for other cutting. I’m left-handed so I learned to tilt the head in a particular direction to avoid debris. Experiment first.The double-sided safety interface is excellent though very sensitive if you release the trigger slightly.TakeawaysA fine performing product that is well thought out and well made. Fit and finish of all the parts were spot on.At retail always do comparison shopping, though it still seems a top performer even at retail. Discounted it's quite a bargain.

What a beast for the money. I bought the used like new version for $70.00. It was a new version repackaged, likely a return Item. Quite a lot of power in this thing. I have been using a smaller Ryobi the past few years. I have a corner lot and my back fence line is a smooth 200 ft plus curb side edging of 200 ft.It used to take a hour plus to do it with my ryobi. This thing powered thru it in 30 minutes. Its true the battery only lased 30 minutes but I had just enuf juice to finish. Its also light wt and easy to use. The bump feeder worked flawlessly.Great alternative to the much higher priced units for a small or medium sized yard.

I didn't get to to use the trimmer until after 30 days from purchase, so I can't return it. The battery will not charge. At first it charged a tiny bit, just enough to turn the trimming head a few times. Then dead. Then will not charge. Just gives red light on. A real rip-off from Amazon. I am sorely disappointed. I usually order many, many tools from Amazon but will have to rethink this in the future. Id a replacement were available I'd just bite the bullet and buy it. But it's not available and they "don't know when".Maybe it's a great tool, but with a dead, un-replaceable battery it's a complete piece of junk. Plus the button you have to hold in in addition to the actual trigger is an absolute b-tch for anyone with any degree of carpal tunnel probs. Tomorrow I will either find a way to bypass it or I will destroy it.

The Denali is the most powerful battery-powered electric weedeater I've ever used. It's easy to assemble, easy to operate, and the battery will last through at least one fairly lengthy weed-eating sessions (20 min or so). All of that power does come with shorter battery life than you'd get with a weaker unit. The feeder function works well. The unit only has two flaws: the jointed part in the middle of the "pole" section feels a bit wobbly, and the weedeater line cap is very difficult to remove. I'd buy it again with little hesitation.

I love it when a piece of equipment works, and this Denali String Trimmer does exactly that. Received the trimmer today; it went together quite easily. I charged the battery to full and then took it out for a test run. I have a very unruly and overgrown fence line (135 feet long), mainly because the neighbor does absolutely no trimming on their side. This trimmer took care of the long grass, grape vines and Creeping Jenny with no problem. Using my other trimmer, single string, would take me a very long time to do the same area and did not give me the finish that I wanted. After completing the fence line, I was able to tackle another area of the yard that is difficult to maintain with the mower before the batter gave out. I did order an additional battery so that will not be a problem during peak growing season (summer). Let me add, I am 5' 2" tall and 75 years old and had no problem with the weight or length of the trimmer. It will make my life easier, thank you.
