Sun Joe 11" 2.0-Amp 20V Cordless String Trimmer+Edger

***EDIT - finally got replacement string in February 2020 so I lost the entire season (Minnesota). Once I got the string and replaced the spool, the spool cover BROKE and will not clip on. So now I can't use it AGAIN and the spool cover replacement part is "out of stock". So I've gotten to use this thing a grand total of 6 times in two years. **EDIT - the string for this device is STILL out of stock! Haven't been able to use it since July and they just told me it won't be back in stock until November now! I bought this for my myself and my son. We aren't interested in gas/oil and have a smallish yard to cleanup. We can get the whole back yard trimmed up at least twice on the same charge. It's clearly not meant to cut through thick swaths of heavy weeds so if that's what you want, look elsewhere. This is for grass trimming and edging maintenance and it works great for that. One pretty major issue though - the replacement line is EXTREMELY hard to get. Sun Joe has been out of stock for quite a while as is everywhere else. I haven't been able to use the trimmer for over a month and they won't have any new stock for another 30+ days!
