What Customers Are Saying

Customers overwhelmingly praise this cordless string trimmer for its powerful brushless motor, lightweight design, and dual-speed control that rivals gas-powered models. Most highlight exceptional performance on thick weeds, fence lines, and brush up to an inch thick, with many noting it outperforms previous gas trimmers. The lightweight frame reduces fatigue, while the snap-in head and bump-feed spool with 0.095" line enhance ease of use. Customers appreciate battery compatibility with existing systems and report sufficient charge after completing full yards. A few mention battery life concerns, but overall reviewers consider this a reliable, low-maintenance replacement for gas equipment.

Awesome edger

Would Recommend

Very good trimmer, edger, weed eater. Relativley lightweight, and easy to assemble. Comes with two batteries, and has two power levels or speeds. It works very easily, and cuts very well.

Solid, and efficient but less versatile

Would Recommend

Good, lightweight battery option for trimming. I have a decent sized yard and can get through the whole property on about half a battery, sometimes I use the same 5ah batteries for the mower and this with no problem. Only complaint is that it’s tough to use as an edger without buying the interchangeable attachment separately. Other trimmers I have used will allow you to flip the head over for edging, and you can with this attachment, it’s just a little cumbersome.

Fantastic

Would Recommend

Just as powerful as my previous gas version. Battery life os pretty good. About 45 min of solid nonstop work. Then, just replace batteries for another run. The attachment options are also nice. The pole saw worked fantastic for some low hanging tree branches. Great product. Highly recommend.

Powerful Lightweight Weedeater

Would Recommend

Light weight and as powerful as gas weedeater. Was able to weedeat boarders of entire yard on a single charge. Fast recharge. The universal connect easy to swith from weedeating to other functions. Like the two speed levels for thicker foliage.

Weed eater is super easy

Works well, both batteries likely needed

Would Recommend

It seems well built. It trims grass fine and is fairly light weight. It comes with 2 batteries and charger. Both batteries can be used at the same time, which are needed in order to trim a 1/3 acre lot. One battery will not do it.

Battery Wouldn’t Charge – Very Disappointing

Would Not Recommend

I was really disappointed with this product. The battery wouldn’t charge at all, which made it impossible to use. I expected better quality and reliability. Unfortunately, I wouldn’t recommend this based on my experience.
