Life saver...literally!

Our aging Cairn Terrier was diagnosed with diabetes about 5-6 months ago and she really struggled with the insulin vial & U-40 syringe method. Our vet wasn't familiar with the VetPen, but she had us get it, bring it in, and then monitor our dog on it. I honestly think it delivers better than the standard vial and the needle is smaller than the U-40, so there isn't as much pain involved. We are such believers that we bought an extra pen just to have on hand. If you have a diabetic animal, this is the way to go.

Delicate and poorly made

178 dollar for something so fragile. One I can admit it slipped from my hands and that's on me. The second one I bought lasted barely a couple weeks. The lid to the pen was loose and the thing slipped right out and broke again. For the record, I had the lid completely on. It was loose no matter what. Now I have to shell out even more money in this bad economy. Sadly, there is no alternative to this pen and no seemingly possible way to get replacement parts.

Not for us

The "click" noise is definitely not the sound of a pen. It's much louder. If your animal startles easily or doesn't like loud noises, this is not for you.

Good investment

I was weary because of the price but overall I really like the pen version. Less needle biohazard and waste. I don't waste any vials because expiration like I do with the 10ml vials. My cat uses 3u twice a day. There's little difference giving the insulin for me as my cat isn't one to try to run away. He doesn't care if I poke him. Just note, you do have to wait about 5 seconds after injection before removing the needle to allow it all to be deposited. I give it 8-10secd. There may be differences in how fast it comes out as I have removed it too soon. Also, I tried to have my dad learn and it was difficult for him to use but I suspect he would have the same if not more difficulties with the syringe. 1 thing I didn't like was the glass vials are not drop proof. I drop one and it broke so I wasted a whole vial. There tends to be a few units left in the vial when it finished. I used my old syringes to draw up his dinner dose. The tiny blue zipper case is kinda useless because it's too small.

the greatest

This is my third purchase of the vetpen, I absolutely love it. It would be even better if they would make .05 dose in the 16 units.

So glad I bought it

After several weeks of dealing with syringes, needles, air bubbles, trying to hold the dog still as well as insert the needle and push the plunger at the same time, I was beginning to wonder how long my dog London and I could keep this up. I found this Vetpen and just LOVE it. It stays loaded with insulin for at least a week and all I have to do is prime with 1 unit, dial the dose, insert the needle and press a button. I find it so much easier and more convenient.

Great tool!

I love the VetPen, because I have MS, and my fingers don’t work so good all the time, but I am having trouble getting the needle off. The two needle removing devices are not working, and I have to unscrew it by hand, which is hard and sharp. Am I the only one who has a problem with this?

Not worth the money

It’s not worth the money, it’s more difficult and takes too long. My dog is the biggest wiggle worm and I was told this was going to help. Well it’s worse, and now I’m out all the money I paid because I can’t use it on him. Don’t buy if your dog isn’t going to sit still for 5 seconds with a needle stuck in them. Expensive and useless.
