Lightest Electric Toothbrush that works well ??

I used to bring my Sonicare. 4.6 ounces. Charge lasts maybe 2 weeks – 28 cycles? I think maybe it flexed between the body and the head, started obnoxious vibration, bought a new one Now I just use manual brush. Make sure you do 2 to 3 minutes. Focus on teeth at gum line. Try not to apply too much pressure to gums. I use Sonicare at home 24 days per month. The dentist said my teeth actually looked better last time. Manual brush is just as effective if you use proper technique. With Sonicare, the technique is easier.

"Those promulgating 'sand and a finger' can leave by the back door :-D" Damn! That's what I've been doing wrong! I thought the 'sand and a finger' was to take the place of toilet paper. So it's toothpaste! That explains so much….

Dual use, Doug, dual use Anyone got a source of UL sand?

Well Doug… 'Whither Manners' ? – it appears they do do

Im sure you could get by with a good quality "manual" model, unless you can find one with a flashlight :)

Not sure about "lightest" but I use a Oral-B brush daily, comes out to 2.1 oz with a standard AA. Not sure the name of it, got it at Target for around $5. Non-replaceable head, single AA battery, quite travel friendly.
