Just a quick question to those who use a handheld device to monitor their own fev1 levels. What device do you use/recommend? (preferable available to buy in uk)
I used to just use the nSpire Piko 1 Hand held Peak flow Meter see here: ssemmthembu.co.za/index.php...
Had it for about 3 years but went and dropped it so looking for a new one or something similar, any recommendations? ;-(
