This is a 5 STAR company. Their product is the best solution for eye drops. I have Glaucoma. My surgeon has me on daily eye drops that are expense. The Mfg puts the drops in a horrible container. You must squeeze so hard that the liquid come out in globs. Nano-dropper solves the problem brilliantly. BUT you must make sure you purchase the right size. 15mm or 14mm. I received two 15mm droppers from one of the on line retailers. I ordered 14mm. I contacted Nano-dropper spoke with Andrew. Excellent company service and highly professional. He solved the problem and I will now order all of the droppers directly from Nano-dropper.
