EGO Power+ 15in 56V Cordless String Trimmer Kit

Overall out of the box it looks to be a great sturdy and light weight battery power string trimmer. Worthy of 5 stars. BUT... I have yet to test this out due to this was Black Friday item and now winter time, will have to wait until spring and summer.As of now I was able to check and or test out the battery and charger. Battery came partially charged about 20% to 40%. I decided to charge the battery to full charge thereby also testing the charger.The charger : At first plug in, both red and greed light simultaneously flashes ONCE (a good sign). Upon connecting the battery, the charger started to hum from silent to loud and started to smell like something is burning. ( I got nervous and disconnect and unlatched the battery and unplug from the outlet.). Back to reading the manual (still not clue). But my understanding was the cooling fan. Research some YouTube videos. Conjured up some courage to try again. Plugged in the charger and connect the battery. Same thing as stated earlier. Held my breath and left it connected and allow it to charge (supposedly). I made sure after 15 min. to check up on it just to make sure it had not started to catch fire or exploded. So far so good. After 1hr on the charger, went to check on it; press on the battery power button and the indicator light was solid on 4 bar and 5 bar was flashing (good sign I thought). After 1 and 1/2 hr went back to check again and Bam! battery was fully charged. BUT the charge still was humming, noise was not loud but you can still hear it. Conclusion was that the loud noise was the cooling fan working to cool the charger while it was charging. This needs to be clearly stated in the manual.Once battery was fully charged I decided to dry operating the trimmer, connect the battery and squeezed both levers and Bam!......IT works. Other than that, so far I have a working product/item. Can't wait until spring/summer.Finally : I recommend this.Update (December 2023) : Got a chance to test this item on my backyard in December month. This trimmer works and operation really as expected and better than others I have own. It has power. Did the whole backyard filled with dried and dead weeds (still standing) just fine without using anymore string. I did not even notice that the string was jammed but was able to finish my yard. (Note : Possibly string can be easily jammed or even ran out without even knowing it, only that the string got shorter or too short). The battery used was 2 bars to do my whole backyard. Good sign that one full charge can and will do my whole front and back yard.
