20V 12" Cordless String Trimmer

Where in God's name do I find replacement spool string for this???????????????

I found this string trimmer to be very user-friendly. It's effortless to assemble, change the line, switch to edging mode, and adjust the limiting bar. The trimmer does an excellent job of cutting overgrown weeds and creating neat edges along pathways. It's particularly easy to edge thanks to the wheel. While my yard is an acre, it has hills and lumps that make it challenging to navigate, but with the two included batteries, I can get through it all without having to recharge.

Edit: It seems they have since reduced price and now only include one battery. They sell additional batteries for $30

This is a generic electric trimmer. The unit came with three pre-filled string spools, a battery, charger and of course the trimmer. It was easy to assemble and the trimmer handles and boom can easily be setup for people of varying heights so they don't have to stoop to trim. it also quickly flips into edger mode and a fully charged battery can run this trimmer for a whole ten minutes of continuous motor operation. many small yards and garden areas can be trimmed in much less time, especially if you're not spinning the string while walking from one area to another. If it lasts a few seasons I would wager it is well worth the price.

This product is an adjustable weed trimmer and edger, with two batteries, a charger with wall plug, and two extra coils of line and a set of wheels for edging.
Assembly was simple and straightforward with no issues.
The product has an adjustable telescoping shaft and an adjustable handle. The trim head is adjustable and the handle rotates when switching from trimming to edging.
The nylon whipcord extends 6 inches from the motor shaft, giving a useful trim area of 12 inches.
I ordered the battery powered trimmer to replace a gas trimmer for the cabin up north. It is part of an overall strategy to replace gas powered devices with battery powered devices. The reason is because it is barely practical to have gas devices when they are seldom used, given the amount of maintenance gas engines require on a yearly basis (fresh gas, new spark plug, etc.). Electrical devices eliminate all of the maintenance required by gasoline engines. Odorous portable gas cans are eliminated and replaced by batteries. The disadvantage of LI – ion batteries is they occasionally spontaneously combust, which is not an issue with gas cans in normal storage. I did not feel comfortable leaving all of the Li– ion batteries unattended at the cabin all winter so I brought them home, which was not be ideal as because with several battery powered tools the number of battery packs quickly multiplies and they are heavy for their size.
In operation I found this trimmer to be relatively powerful though not as powerful as the gas trimmer it replaced. Nonetheless it had adequate torque to handle the tall grass surrounding the cabin and the grounds. Battery life was good, about 20 minutes. The second battery included with the product doubled the operating time.
Overall the benefits of this product include it’s lightweight and minimum maintenance make it a winner as a replacement for heavy old style gas powered Weedwhackers.

I really like this Berserker string trimmer. It is solidly constructed of quality materials. The bulk of the parts are high density plastic with the shaft and some components (like the collapsible shaft) made of metal. It was easy to assemble. It comes with a single 2.0 A 20Volt battery. Replacement Berserker batteries and a higher powered battery are available for separate purchase through Amazon. The battery does have a very nice press to see the amount of charge button on it.
I am impressed with the power and effectiveness of this setup. I used it for about 20 minutes trimming very thick and heavy vegetation before the battery ran out. It took about an hour of charging to bring it back to full charge. The spools of string are not like the old style single strand plastic string. The cutter is like a twisted plastic covered pair of wires. It comes with two extra spools of the cutting wire. I have not seen this type of cutting wire in my local hardware store but it appears to be very robust and the three spools that come with this trimmer should last a long time.
