Not very impressed with Pulse HR

I've had my Pulse HR for coming up to a week. I am wearing the watch plenty tight enough before anyone suggests that I am not doing that properly.

Sleep. Either I'm asleep when I'm watching TV at 7 pm or I'm awake at 2 am when I'm firmly asleep.

Steps. Now, I know step count on any tracker has a margin for error but the margin here is HUGE. If I'm carrying something while walking, no steps are counted. If I just do a few steps then stop (e.g. when cleaning my house), no steps are recorded - in fact two hours of deep cleaning that left me breathless and sweaty was recorded as about 10 steps and no active minutes - an alternative tracker recorded several hundred steps and a sustained level of activity.

Heart Rate. Completely inconsistent recordings with other measuring devices, including the Withings blood pressure monitor.

Missed opportunity. There's a chart of heart rate while sleeping and a chart of sleep cycles. It would be super helpful to have one overlaid over the other so I could see if a HR spike in the middle of the night corresponded to something.

Very disappointed. I needed a replacement for the Fitbit One, which was a very reliable means of tracking general levels of activity (until it died), and although I didn't care about the HR or sleep aspect I thought maybe I'd like tracking those stats. However, they add no value as the data being collected can't be trusted.I also hate the cheap silicon wrist band, the sweatiness it causes on my skin, the marks on my wrist from making sure it's on tight enough. There are no fabric straps available that allow the skin to breathe and a watch shouldn't need to leave marks in order to function.
