I used the Fitbit for several years but honestly it really pissed me off for several reasons. I had the Fitbit Charge 3, which apparently has a screen that just fails after about 12 months and goes completely dark. The first one went dark about a week before the warranty ended, so they sent me a new one to replace it. This one worked for just over 12 more months and its screen went dead as well.

I continued using it just for the sleep data, but that was wildly inaccurate as well. It did manage to known when I fell asleep and woke up (except it thought I was asleep when meditating) but it was far under-estimating my deep and REM sleep. I was freaking out a little. It also thought I was getting sleep apnea. Just so many problems. This one is way more accurate! It does cost a monthly fee though.

we have talked about getting a treadmill this year

We have a couple of Spin bikes in the garage that we never seem to get around to using. We got some clip on pedals and shoes for it as well which I finally installed. I also made sure the garage was clean and clear so we have no excuses now! I have GOT to get in shape. At our age we can't neglect it or will suffer a lot later.
