Greenworks 40V 13" String Trimmer

I bought this to replace the 12" model from 2020. That model, I had modified to be more similar to an old B&D that I had. The B&D had a simple slide coupling on the shaft by the head that allowed you to rotate the head for edging, something I missed on the Greenworks 12" trimmer. My resolution, disassemble the shaft connector on the trimmer, drill a 2nd hole for the locking pop-up. This allowed me to "simply" loosen the wingnut on the coupling, push in the pop-up and rotate the head. Not great, but honestly worked great. When the 13" Greenworks trimmer / edger came out, I said I would give it a try. I read many many review, many bad, yet still bought it to see if I would like it. Note that I have not used for any longer than 5 minutes yet, so I will update after a long use. Observations I have made so far: 1. Heavier than the 12" though it is quite shorter. Note the descriptions say otherwise, yet if feels heavier to me. I believe that this is a balance issue. I am about 6' tall and find it uncomfortable to hold. With the forward grip as far forward as the coupling, when held at the grip, the trimmer was vertical. My old 12" is nearly horizontal with the same test. 2. The Trimmer is single line, meaning only 1 line is out and cutting vs 2 on the 12" 3. The spool cover is very difficult to remove compared to the 12". Not sure if it is "newness", but I almost opted to grab a tool of some sort to remove it. 4. The battery is on top of the handle portion, such that it is right where your forearm / elbow want to be. This is the biggest deal breaker for me. On the 12", the battery went in the back like this one, yet it went straight back. On this one, it sticks up, forcing you to bend your arm to hold it. After 45 minutes of use my arm / elbow / wrist were quite sore. See the attached pic. 5. It takes thinner string than the 13". I did not notice this on the spec when I purchased, not really concerned, but it should be noted. The 13" takes .0625" dia line. I found that this line broke much quicker during edging. I found myself constantly advancing string. 6. There is a wheel on the guard for edging. Great idea, however, the distance from the wheel to the guard is about 1-1.5". As a result, if you have thicker lawn, the guard is going to get caught on the grass. I used the wheel about 10% of the time, found it more trouble than it's worth. 7. The change from trimming to edging is easy, that part they got right. 8. I found the spool cover very difficult to remove. It appears that the holes for the push in tabs are further down the spool than on the 12" such that they are close the hub and you can not get good leverage to push them in. I did this 5 times and nearly went to get a tool to have handy for the next time. I ran this for about 45 minutes, maybe 5 minutes trimming, rest edging. I really wanted to like it, but that is not the case. One comment others made was about the string not coming out of the hole. I had to remove the cover and reroute the string 4 times. I found the issue to be the factory wound string was too tight. My takeaway from this trimmer is that they had a lot of ideas and slapped them on it without proper evaluation. Some of the quirks I could over look, but the battery placement / orientation was the deal breaker for me. Since I paid about 55 for this, I will either sell it or possibly see if I can gut it and use it the articulating head with my 12". Speaking of the 12" , after running the 13" for 45 minutes, I used my 12" for some trimming I forgot about. It was so comfortable.
