I find that after 5 minutes when I can /feel/ the sweat on my skin it comes to life and work like a
charm after that. Since it undoutably works by measuring the change in resistance of the skin right
next to the sensor (which probably just has a small magnetic field) or detects the changes in
voltages by the heart THEN having something with lower resistance (like sweat) compared to dead skin
is going to make it work.

The timing difference is probably down to me sweating more quickley (I've only used it when on my
turbo trainer).

I'm guessing quality at this stage (given I was impressed by the watch and transmission and
sensor+strap for the price) is in detection and its sensitivity.

Oh, and I bought too many (on purpose) so if someone would like one then get in touch, am in
Cambridge.

Although the sensor does look bad, its working fine for me now. I actually place it higher (ie on
ribs) than the one I used to use (a cardiosport).

I've been playing with it and its got a ridiculously large set of features. I've never had a lap
timer before, and will probably use it to time different stretches of my commute (ie the big
long hill). I now realise its got an average heart rate per lap, so I could look at that for
each stretch.

Ah, the fun of gizmos

I returned mine yesterday, no problems, and was given a refund. It was reported on the returns
receipt as 'delayed start'. I liked the features, and for the money, it would have been fantastic
value, if the monitor had been more responsive, but I wanted to know my heart rate before, and
during the start of exercise, and not just after 20mins. My friend is happy to work with the
limitations, and says he will be keeping his.

Ah, the sweaty man was right.

I lick the contacts before putting it on, and put it on without sliding it. I have to do this with
the cardiosport too - I imagine its common to most HRMs.

It also doesn't work if you go out first thing in the morning (honest) without showering - ie you
are already rather salty and sticky.

(Also near cordless computers or tram lines)

My £17.99 one from Lidl (last year's model) works fine near the Sheffield tram lines. Good job as I
cross them 3 times and follow them for a mile on my commute!

Anybody else irritated by the way Aldi have something then don't a week later ?

Is some of it bankrupt stock or do companies like Crane sports only produce stuff for them for
short periods ?

No. It's how they keep the prices so low. Expecting such low prices *and* long term availability is
unrealistic.
