I had/have an older version of the Husqvarana (about the only time I have used q without a u after it). It worked well enough for several years. But got a bit temperamental, bit of a PITA to start. Plastic shielding broke easily, gas tank vibrated loose. But it was a decent trimmer for a few years.
Have a larger Hasgvarana chain saw also. Bought it because Husky saws were a respected brand when I cut wood/trees for a living along time ago. Very disappointed with it. Still have it but it doesn’t compare with the Sthil 039 which is a bit bigger.
I replaced the trimmer with an Echo. The 2 most used trimmers landscapers seem to have on their truck are Echo, then Sthil around here.
I bought an Echo SRM 266-T. It received very high consistent reviews, from the pros and weekend warriors. The “T” is more powerful than the standard 266.

I did not buy mine from H-D. Got it at my local Farm Equipment dealer. It cost a few dollars more but they work on, repair the stuff they sell as an authorized dealer. The box stores do not. They send it it out to who ever the local bard X repair shop bid the lowest for the work. Found this out the hardway.
Have only been using the Echo 2 years now but it is REAL easy to start and runs very strong. I also use a “cutting wheel” on it for the “woody” weeds. These can be had for just about any trimmer. But they add a lot of weight, spinning torgue and can stress/snap the “drive shaft” cable on lesser trimmers. Ask me how I know.
The “handle bars” and harness can be bought and added to just about any trimmer.
Just my 2 cents.
