virgin active bf machine

sup guys. just wanna find out exactly how accurate those bf% readings are on those machines at virgin. go there on mon then on wed my bf is up or down, is water retention from creatine maybe the culprit or just dodge machinery or does bf really go up or down by as much as 1.5% in 2 days??? thanx

I've just those machine only twice in my life and both time I took three readings in a row.

I went from 23% to 12% to 16% so honestly its the biggest load of kak ever!

That bf part is not accurated at all. I use it mainly for the blood pressure function

LoL, it told me I am 20% too, after I did a caliper test and came in at 9%, then it tested my blood pressure and told me I am 115 / 80 something, I went home and tested it and it was on 155 / 62. Also I am 191cm yet the machine told me I an in my lower 180's
