As you may remember, from time to time we have had some difficulty with the fabric accepting the dye. This in no way affects the performance or life of the cap. We will, however, arrange for a shipment of a replacement cap to you; please advise whether the cap should have 10 electrodes or 20. It would be helpful for us to know the batch number for the cap; this is written on the tag in the back of the cap.
With reference to your EL 16002, we have never had a question about the thickness of the disks. As the disks are compressed during use (to the thickness of the electrode mount) we're unsure how this could affect the disk's performance. We will, however, send 7 packages with your next shipment as requested.
