This novelty is an invention of Medwork Instruments, so you won't find it anywhere else, but also for that reason, there's no standard established for it. So we would like you, our customers, to tell us what you think. We feel it is your responsibility to make the medical community as good as it can be - it may sound like a confrontational and bold statement to make to a perspective customer, but that's why you got into the profession in the first place, right? You must believe you are better at filling your shoes than someone else would be. (That or you did it to make lots of money.) It is our responsibility to fulfill your needs and facilitate your doing so, (and if we don't, we won't make ANY money). But regardless of whose moral obligation it is to do what, the fact is that in order to do his job, the medical professional must have the right tools, and it's not his job to make the tools himself. And how are the suppliers to know what these tools should be unless you tell them? We need to find out from you what you think of it. Is it good? Bad? Just plain ugly? Let us know by phone, fax or e-mail! And when you place your order, let us know whether you want them with a little airspace at the end or permanently affixed, or if you don't want them at all, by providing this information in the comment field.
