Great product. Definitely would buy another
This is a great weed wacker. Even after sitting for 4 or 5 hours after running it, it starts first pull. The throttle lock is amazing. Makes it better to focus on the cut rather than the right throttle amount. The head is a little tough to string up but not the worst. I actually switched the head out with the echo speed feed head 400. The only thing I would recommend is to make some interchangeable attachments for this. Such as a metal blade edger, hedge trimmer, pole saw. If you guys have some or know of some that would fit this product, please let me know. I will order them. I run a lawn business and use those attachments on my other trimmer daily

works well, but assemble the bolts tight
first use of it worked well.. second use, i flooded the engine, opened the intake full, after trying to pull the starter a few times to clear the engine— then it worked well.. power is good.. was able to cut down 1/2 inch weeds and branches deciently. rev it to full power and chop away. so far so good.. the tank i got about an hour of use. was able to cover a half acre. the blade at full power stops when it hits fencing — i like this feature.. i am not afraid to get near it to chop the vegitation. the blade is ‘soft’ so if you hit stone it will deform. after a few uses and hitting rock and brick lost about an 1/8 inch on one blade and bent ends on the other. when it hits rocks, it doesnt toss them far, so safe from windows. havent tried the fish line cutter. its a bit heavy, so adjust the arm strap correctly. once set, it works like a charm..

Revised review
I believe in responding positively when a Seller makes an attempt to make things right. Initially, I wanted to return what I thought was a piece of crap. They offered a full refund when Amazon wouldn’t help me. I have had this for about 3 weeks and after deciphering the instruction manual (with misleading graphics on how to attach trimmer head) and reading the fine print on the throttle control lock, I finally attached the trimmer head and can start the unit in about 2-3 pulls. Although 2x heavier than my previous trimmer, this seems to be more substantial physically. My only feedback to Seller is: Don’t hide behind a text/email - ANSWER your published Cust Service number! I waited 2x for 40 mins to be told “you are the next caller” before being hung up on. Hence 4 stars. If you like a challenge in getting stuff to run, this is your item.

Terrible product!!!
This trimmer is trash! After only a few uses I’ve thrown it away! The screw for the guard stripped off, the gas tank cap cracked, & the string will not release. Do not buy this trimmer!!!

2 years owned - reliable trimmer
I bought this on May 18th 2022 got it within a day or so, typical Amazon deliver times spot on I'd say. I live in a rv at a trailer park. My yard is 1/4 acre and I cut the whole thing twice a week. This trimmer easily splits in 2 for optimal storage. This makes my life easier being just a gas trimmer. Just over 2 years old and have done regular oil changes at the end of each season, store with no fuel in it and it starts second pull after choke. The only bad I've dealt with is the head. Pretty cheap. Do yourself a favor and buy B07VYCZMR9 head replacement and get some quality string it'll last for years obviously.

Like it but it’s day one
Got it and within 20 minutes I was using it. I think the brush blade is too heavy and cause a wobble but it worked pretty decent. I was really surprised. Btw I’m 6’2” and 230 and decent shape. This gets heavy. Also I was cutting fur tree limbs (small) over my head.

Great weedeater but....
Was excited to get this weedeater. It's a good, strong running weedeater but refilling the string is a HUGE pain in the butt. I've owned many in the past and this is by far the worst way to restring a weedeater. If you are thinking about ordering you might aswell throw a speed restring head into your basket as this is terrible.

VERY POWERFUL AND NO OIL TO MIX WITH GAS!
VERY EASY TO ASSEMBLE. DON'T REALLY NEED INSTRUCTIONS. THE WEIGHT IS PRETTY HEAVY SO NOT FOR WEAKLINGS. GOT TO USE WITH CHAINSAW BLADE WEED/TREE EATER HEAD. STARTS EASY AND RUNS LIKE A CHARM. WOULD RECOMMEND FOR HEAVY USE.
