I bought 25 of the purple bulkpaqs with the white tops, used them all and they worked fine. I then ordered another batch and they're clear on the top rather than white. Now these ones are MUCH more fussy and i would say only 1 in 4 works. Has anyone else noticed that many of their disks work at first and then become temporamental after a couple of weeks?
Is it known that these clear topped bulkpaq generation 3's aren't up to scratch?
