Bests & Worsts Reviews from Amazon

I just received the trimmer. It appears okay but is missing a very important feature. Please see the attached snapshot of a caution found in the instructions. It does not automatically shut down the charger when it is fully charged. Instead it gives us a CAUTION! be sure to take it off the charger when it is fully charged. So I couldn't just put it on overnight since it takes about 5 hours for a full charge. How would anyone know how many more hours it would be until you gave it some attention the following day. It also says to recharge it after use so it doesn't get stored for a long time in a discharged state. So if I use the trimmer for a half hour and it doesn't have the automatic charging shutdown feature, am I supposed to watch it for hours when I go go recharge it. And, again, who knows when it would be convenient to look at the thing after charging it - - every time. The charging shutdown feature is on our smartphones, power hand drills, etc. I would say that it is just unacceptably deficient to sell the trimmer without the feature. Then just surprise the buyer when the package is opened. I don't think I am being unreasonable. This just ain't fair.
