Love this test. At $2 a test you can test first and ask questions later.
R Cards are easy to use, greatly reduce waste to manage and make our monitoring program possible at reasonable cost
We have used products from Dr. Roth for decades in teaching settings. They are incredibly easy to use and interpret. These products are Godsend, especially to introductory courses.
I agree with Neal 100% - great customer service. I highly recommend these products...I give 6 stars!
Customer service is superb. Hard to find good customer service these days. It appears these people actually care about their products and what people think. Pleasure doing business with them. Refreshing change .
Meets our needs efficiently and effectively at a reduced cost and reduction in waste.
Relating to my review of 9/28/2003, it turns out this was my fault, my previous orders were for 3 ml cards, and this was a 1 ml card. Dr. Roth phoned me up and set me straight. He says you need to let the water gel for 2 minutes before closing the film. This is not convenient for me, so I'll be using the 3 ml cards even though I use a 1 ml sample. I appreciate Dr. Roth taking the trouble to phone me.
All looks ok. This order was send to my Customer in Guyana.
Quick delivery of my order is much appreciated.
