What problems have you experienced with them? This was Filmed in December 2021. Fast forward to 2024 and we are still using these units on a weekly basis. We are doing more tree work and using these less often, but some intermittent issues still persist. Apparently it’s something with the electronics near the trigger …
I still think that this line up is #1 compared to what's currently available in the market. The telescopic features and balance are top notch. We number our trimmers to keep track of them. the Short He3's start in the 30's and Long Ht4's start in the 40's.
Since then, I have used STIHL, EGO and ECHO trimmers as well.
