Got it on special and it was well worth it. We have purchased a lot of Blingles products and refills and the first ones are still in excellent condition and were done well over a year ago. We have put them on bike helmets, PSP Cases, Diaries and more.
The only improvement I think they could make would be to have more glue rolls in each pack. You can create your own designs as well as use their templates and there are plenty of jewels just not enough glue rolls. Admittedly I haven't looked to see if you can just purchase glue rolls.
