To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Was a bit sceptical as it seemed so cheap compared to the actual Blaze itself and when it arrived it came in just a clear box with a tiny label that anyone could have printed. But it's charging my Blaze right now as I write this review, actually just stopped to check it and the unit is fully charged, which seems really quick. So at this price, what's not to like! Arrived today, seems great so far.
I bought this as a replacement charger as my blaze charger was wearing a bit... I charged my blaze with it and the next day my fitbit went haywire and the lcd screen disappeared... I tried again today and the screen came on as charging but after two hours the screen showed an interruption in the charging circuit so I am assuming it has failed. Had my blaze for 4.5 years and it worked OK until I used this. Not happy but it is a non fitbit item so buyer beware
