Fast delivery and excellent top quality product! We bought a microscope, for my 11yo mini-biologist son’s Christmas present and I am amazed at what we are able to view -rotifers, nematodes, paramecium (I have had to cast my brain back to yr 9 science!!) from samples he has taken, as well as close ups from pre-prepared slides we also purchased -insects, brain, blood. He is addicted to seeing this other microscopic world opening up, & learning so much as a consequence (& so is the rest of the family)! Thank you so much for providing a quality product & fantastic service! Best Christmas present ever!
