They had ALL the items I wanted to store my insulin in keep cool cases at very competive prices.I bought two icool cases for my two pens=Humalog & Lantus(one case on the the go & second for back up pens) & two Die-Pak blue cases to store ALL my Diabetic stuff(testing equipment,needles,spare insulin as it also cools with gel packs) one on the go & one back up.What was really great was they also had the the really good quality 6 hours gel freeze packs by icool with the durable plastic outer case as the one supplied with the Dia-pack is just a cheap plastic outer on the feeze pack. The 6 hour packs were not cheap but you get what you pay for & these will last years by the look of them.I was especially pleased everything I needed was in stock & ready for shipment as a one stop shop.Customer services even phoned me up the next day to ask me what I wanted to do over one 99p item being out of stock & they sorted out very quickly a mistake I made in putting the wrong number house(Typo)-before they dispatched. I already have the evaporative(gel crystals you soak in water)case to keep my insulin cool but decided 6 hour cool packs are more efficient(I bought four for the Dia-pak(one in & one spare for two cases) & two spare for the icool as it came with one pack per case already.This gives me 24 hour rotation on one case should I need it or double the freeze pack if travelling in a car in a heatwave..........as long as you have access to a freezer?& if not I will use the evaporative one. When it comes to keeping Insulin or other medication cool you cannot have too many options as heat will render Insulin ineffective....it happened to me once & you start going Hyperglyceamic. All in all it was a very happy chance coming accross Molly Mojo as I am childless by choice but THEY SELL THE BEST TWO TYPES OF DIABETIC CASES!!!!!!!!!& provide a GREAT service......I got a refund straight away on the 99p............some companies have made me wait weeks for £hundreds!
