Levenhuk N20 NG Prepared Slides Set for Biology and Physiology with Blank Slides and Cover Slips in The Kit

A nice set in a compact plastic case with plenty of room for your own slide creations. Much more complete than smaller sets.

I order the N10 which were sold by Levenhuk and was fine. However, when I ordered the N80's which were sold by VirVenture they had this brown discharge inside the case that holds the slides. I reordered the slides and they were the same with brown discharged inside the slides. VirVenture wants me to pay postage for return. I thought if it was Prime and there would be no hassle return. I called Amazon and went through some grief with them but they refunded my money. I also tried to call VirVenture to find out what was going on with their slides, as I think they are old and that is what usually happens to old slides (they break down and leak) but no one picked up the phone. When I called there was just music, I waited a few minutes to see if a machine or person would pick up but no one and no thing picked up. Not happy with Amazon or VirVenture. More and more I find quality control with Amazon's sellers and Amazon's representatives are falling below the bar. Will throw these slides in trash and purchase another set from another source.

Very well prepared and stained. I use an Olympus MIC adapted to take a smart phone for grandchildren and the pictures are astonishing up to 300X. The blank slides are an excellent inclusion.

Preparaciones meticulosamente preparadas de forma profesional. Limpias y son lo que anuncian. Ya había adquirido la preparación 18, y esta tampoco defrauda.
