“Misaligned battery tube prevented cell insertion without modifying with a file. On board charging measured at 2.5A which is ridiculously high for 18650 cell. Well above manufactures maximum, risks rupture and guarantees short life. 1A is safe and will give good cell life. Confusing interface, no memory of power lock when cell changed. Impossible to read battery level without a magnifier, the old sliding bar display was good so why change it. Other than that, it works. There's just too many negatives for me to enjoy using it or recommend it.”
