From this review of the new Fitbit smartwatch
… the Sense has a “solid-state button” on the left. It is, essentially a small, sunken area with capacitive sensing. When you press it with your finger, the watch vibrates, giving you the impression that you’ve pushed a button…
[But] I do not like this solid-state button. Unless you cover the entire button with your finger or thumb when pressing it, it won’t register, which leads to a lot of fiddling. Do you know what rarely suffers this kind of problem? A normal button. Another issue is that at certain angles the left side of the watch will just happen to press into the flesh of my forearm, which the Sense kept reading as a long-press, and so Alexa was constantly popping up and listening for a command. It happened so often that I eventually disabled long-pressing all together. Not ideal!
When you upgrade to a new version of the product you already use, it’s annoying to find that you have lost functionality, especially everyday functionality, because the company decided to pursue something ‘cool’.
I had recent first-hand experience of this. I can set my Fitbit Charge 2 to display the date, time and my progress towards the 250-steps hourly activity goal. It’s perfect and I rely on it constantly. Got a Fitbit Charge 3 for the spouse. It has a much wider range of ‘faces’ you can configure and set. None of them has the activity goal on the home face. Others are similarly annoyed (Fitbit Forum, Fitbit subreddit). It’s impossible to verify this before purchase, and there was no real reason why Fitbit couldn’t have also made it available.
