This was our first order with Dip-Slides.com Having decided that the subscription service was the most cost-effective way to obtain this product we went ahead with our order. The whole process was logical, easy to follow, and confidence inspiring. Our order arrived 3 days in a very well packaged carton. These test kits are something that we have experience with and we have absolute faith with this product. Now we can continue using what we know at an advantageous cost. Time will tell if the subsiquent re-supply items arrive at our elected renewal period, however the initial impression is extremely favourable.
