“The unit is performing great for me. I haven’t had any problems with it, and it fits the 1 ml ampules perfectly. It is a great product and makes opening ampules much easier than other products I’ve tried. I’ve opened over 100 ampules with it already and zero defects!  Thank you!”

“ I have been using the ampoule opener on ampoules that do not have a dot but a band around the neck. It was very difficult to open them even with a file. Your opener solved the problem.”
