OK,
I went to Costco in October and bought a new Wahl beard trimmer (lithium model). Brought it home and charged it up and tried it out the next day. Trimmer worked OK, but after changing heads, (has multiple heads, etc.), and using it for maybe 5-6 minutes, it would not shut off. They supply a little red plastic button to insert in the base (where the charger plugs in).........the red button is supposed to be used while "traveling" to ensure it doesn't start up accidentally.
Well, that red button is the ONLY way I could shut down the device. Matter of fact, the next time I used it, the red button would not even stop the motor. I had to just let it "run down" out of battery power on its own.
Sent it back for replacement/warranty service. After 23 days, they sent me a brand new unit (stainless steel model) actually an upgrade from what I purchased.
Sadly, same results. Charged it up, used it the next day and it would NOT shut off. Used the red button to stop it and tried to see if it would shut down after an hour or so..........Not so. Tried it again after 4-5 hours.........same results.
Amazingly, the next day...........I tried it by pulling out the red button and oooooooooops, the damn thing did shut off.
So I used it as before and low and behold after 5-6 minutes of usage it did in fact shut down via the switch as it should have.
So, now I'm not sure how reliable it may or (may not) be and have tried to contact customer service and finally had to hang up after over 15 minutes on "hold". I will be contacting them again tomorrow or Wed. as to what is next, they clearly have a switch problem.........with their new Lithium trimmers.
