I saw this on sale a while ago but was holding out doing my research.
Didn't pull the trigger first round as I cannot any GC at the 15% sale. Then also miss out on the Myer GC bonus $10 per $100 deal too. Worse it went OOS on the main Myer site but apparently you can still order if you have the link. White version is linked at picture. below link is the black one. Note Sage/Grey Silver version is not on sale.

Price Match & Ultimate GC at JB Hi-Fi for $269.10
I have the black one loaded on my phone and show the girl in JB Hi-Fi Galeries Victoria. Promised a price match so I ran across to Woolies and got $300 if Ultimate Kids/Teens GC (can't remember which, Home also can use in JB). $30 rewards cash hit my account before I was back in JB Hi-Fi. Whole thing done in 10 minutes. This is much better than stuck with $30 Myer GC.
I start using it for a day, my only complain is it only takes SPo2 readings while you are sleeping. I am not an exercise person, I was looking for something that track sleeps, SPo2 and ECG. At the price of a Charge 5 I think this is an excellent deal.
Sense works both with Samsung Galaxy and Iphone which is a big plus as I own both. Apple watch only works with iphone and Galaxy watch4 is only Android (with some function only work with Samsung S Series). There is a 6 month free trial on Fitbit premium which you can activate anytime you want.
Got one when my charge 3 died. Very happy with the sense. Got it cheaper as my charge 3 had died and Fitbit issued me a 50% off voucher / replacement charge 3 voucher (as my tracker was still under warranty) through chat.
