'dope testers' in Holland

[VinylChef]

Um, I posted about this subject a couple of weeks ago.
Sorry for being repetitive, but I need some advice or collaboration from people who have bought what's called a 'dope test'. You buy them from shops in Amsterdam mainly.
The instructions indicate that it works basically the same way with the same colour reactions as the classic EZ tester. However I have tested two pills with it. Two pills which appear to be quite excellent. Double sided raised Versace's heads, orange. And grey triangular double sided Supermen. Both pills rate very well on pillreports. But when I tested them there was no reaction. That's right: no reaction whatsover. Does anyone know what the deal is?
Any info appreciated.

Just because a pill is well rated in pillreports is absolutely no indication as to whether you've got a good pill or not. Every batch of pills is different, last month's Red TT won't be the same as next month's Red TT. Pills vary greatly from batch to batch and from region to region. The stamp is ZERO indication as to the quality too.
So you either got bunk pills or your testing kit isn't working like it should be.

I've used the 'dope test' testers over the last couple of years and had positive tests to almost all tests. Maybe you've got a dud tester.
