Novopen 4 Blue Reuseable Insulin Pen for use with Novo Nordisk 3ml Penfill cartridges

Not as well made as Novopen 3 - more plastic, not engineered, feels very cheap by comparison. Also, the case of Novopen 3 allows for a spare penfill cartridge and 3 pentips - all highly useful when going away for a day or two whereas this case is not helpful at all.

Excellent product, smooth action, it can tell you how much you have left (which is great for me as I travel a lot and is always useful to know if you need to an additional cartridge on a trip). high quality build - I only purchased this one as I lost my original which I had for about 3 years with zero issues....

My dad is happy with it no problem so far, he was using the 5 and was so frustrated with it as it started to get jamed after few months of use. Hope this one is better

I prefer this to the previous version - the action is much smoother, making the injection far more comfortable. The dosage scale is also much easier to see, which means I don't have to find my glasses every time I need to inject.

Fantastic and easy to use!!!! Thanks very much....it's to replace the broken pen!!!! The colour is awesome and very light

THIS IS THE MOST UP TO DATE TYPE 1 PEN ON THE MARKET AND AFTER 35 YEARS A TYPE 1 DIABETIC IT IS WORTH INVESTING.

Stylish and very functional with easy to read dosage units. A big improvement on earlier models which I thought were excellent anyway.

Excellent Novopen, positive action and easy to read scale.
