Dont buy fitbit charge 5
I followed the advice to take off when showering and even did not submerge in water.
It still died in 6 months and I was out of luck since without receipt, fitbit will Not warranty.
They have my device tracking that shows I used daily for 6 months and then stopped logging / working.
I believe a company given todays tracking should stand behind its product, needing a receipt is just a way to lose more customers. I had a fitbit 4 and now 5 and will NOT buy any more fitbit's.
