What is it exactly that you are hoping to learn? Asking whether somebody likes your pen or not is not really going to give you very much information. The way I see it, (and I might be totally wrong, so feel free to correct me if I am) there are only a couple of things that you could possibly ask - Would you prefer a different material/pen style? and How many would you like to order?
Questions about quality are extremely subjective. The easiest and quickest way to judge quality of a turned pen is to examine the fit and finish. These are also pretty objective. Regarding the fit, there is either a noticable difference at the transition from blank to components or there isn't. If you're not sure, a pair of calipers will not lie to you. The finish is slightly less black and white, but still fairly objective. Are there any noticable flaws in the finish? If you are using a CA finish, it should be equally polished all the way around the pen with no pits, ridges, flecks, dirt spots or cracks that change the way light reflects off the pen. Any other finish should be just as uniform. Subjectivity only enters the equation when you consider which type of finishes are preferred and whether or not the finished used will be durable enough. Shape of the pen is pretty subjective, although most seem to dislike the fat or bulgy pens, especially on a slimline. Material is also subjective. Some only like wood, others only want acrylic, others will only be interested in paying for a bullet cartridge pen with antler, it just depends on who is buying the pen. Pen kit preference is similar to material preference. If there was just one universally loved kit out there, there wouldn't be as many options. I'm sure that if you picked what you believe to be the ugliest possible kit out there, somebody else would come back with a list of reasons why they love it. One thing that will make a difference in which kit you use is the plating of the kit. Nobody wants to pay money for a pen that loses its plating after 3 weeks of use and looks cheap (regardless of what they paid for it). By always buying the most durable platings that you can, and you don't have to worry about that issue.
I hope this makes sense, but I don't want you to struggle through making some survey just to find that you haven't really gained anything useful from it.
