I would give these an "excellent" if they were more widely available. I have such a hard time finding them. Each store seems to carry one or two designs (and typically not the ones I want). I would love to see Sally Hansen have their own online store with free shipping with a purchase minimum.
I'm not sure how many years I have been using them but I have tried many other brands (including the trendy Jamberry...which I HATE), and these are by far, the easiest to apply, the best fitting, the thinnest and the most durable. They have slight stretch ability to them that allows for better coverage and nail fit. The only reason I remove them is that my natural nail grows out. Two weeks EASY...three weeks the nail has just grown out too far. No chipping, no peeling. My natural nails are weak, and these protect them from splits and tears so they grow out.
The only downfalls is the availability, and not enough styles. Also, some stores keep them on the shelves too long and I have purchased some, on more than one occasion that have dried out in the package. If that happens, they will not adhere...at all. I get compliments galore on them.
Sure, once in a while you get a wrinkle in them and they can take a while to learn to put on well...but not long. Also, because my nails are short, and they have pattern on both ends, I can carefully apply one, trim it, flip it and put the other side on the opposite finger getting two out of each strip. How great is that?
I'm not interested in gel nails and having to have more than one container of stuff to apply or a light dryer or any of that noise. Please don't ever discontinue these Sally and please offer your own online store. It's not useful to have to shop online at a different vendor per style and then pay postage per multiple outlets which often ads up to more than the price of the product. That has resulted in me not buying them and only opportunistically finding them.
