Query: Inject ease

The only issue I had with this product is that it was very difficult to remove the suringe after the injection. I use insulin 4 times a day and each time I was concerned that I would break the product trying to remove the suringe. I did like the fact that you could reduce the dept of the needle into the skin by placing the rings provided onto the injector.
