I have been using this type of product for more than 10 years when they first came available in the USA for use outside the USA only. The Biosure Self-test kit is by far the best product I have ordered for this purpose. The old strip test always left you in doubt how much blood to put in the sample area. This kit takes the exact amount by itself. The same with the test liquid I was always unsure one drop two drops. This kit your put the sampler in the pot and it all takes place automatically. The literature that comes with it is comprehensive, very clear any easy to use. It’s discretely delivered and disposal method provided. One of the best products for self-testing I have ever seen and used. Well done to Biosure for both their product and customer service. Just Google to find it Many thanks.
