Jawbone UP3 Wireless Activity Tracker (various colors) $20 + Free Shipping (eBay Daily Deal)

I worry about this. Ignoring the price, Jawbone has gotten out of the consumer market. If you need a replacement, it may not come in any real time, and I have no idea how long they'll keep their software up to date.

Doesn't let you choose size either. The jawbone I have is a medium.

All 3 Colors come in Jawbone boxes, most of them are sealed still. These have been sitting in warehouse for 2 years and battery may have gone completely dead. Firmware and Software update may be required to Power up. We have sold to sellers who are selling them as brand new for $35-$85 on other marketplaces. Open to accepting a lot offer for 1000 pcs. The packing images you see are actual photo of the Box in our warehouse.

i got one of these for $13 - all these UP3 sellers flooding ebay are completely full of shit.
the bands work fine - but only while connected to usb power, so completely worthless
as an wireless activity tracker. the charging routine faulsly shows the battery if charged,
but the moment you detach the band from usb power - it dies out completely.

fortunately my reseller fully refunded me thanks to ebay's 30 day buyer protection.

part of the scam is how some resellers will send you elaborate FAQ's on how to fix it,
or will tell you if you charge it for a few weeks it will suddenly wake up and charge right
this is all designed to run out the clock on ebay's 30days so you become stuck with it.

think of it another way... back when UP3 was a current model, owners noted the battery rarely held out a year's worth of being recharged and standby - so what do you really expect units sitting in a warehouse since 2015 to be like?

I suggest SD mods take note of this and bann ALL attempts to list out of business Jawbone.

if you want cheap dependable current activity tracker and heart monitor i suggest;

Huawei Honor Band 3 - selling shipped from china brand new under $40

Xiaomi Mi Band 3 - out this May $35 in India, so hopefully under $50 to usa.
