I had to do a quick fix on my polygel reinforced short left hand nails. My middle finger specifically. I didn't want to file it all down and spend more than 45 minutes fixing only one lifting nail. So I broke out my e-file and only took out the one side and decided to fill the missing section with this product instead. And I have got to say, I'm amazed! Unless I'm looking at my nail from the angle I showed in my included image then you can't tell! PLUS, and I'm serious about this part, after a week there's still no sign of lifting. Now for most people this wouldn't be an issue... But.... I'm a hairstylist and I play guitar!!! And this IS my left hand. I use my middle finger almost like a slide when I play. And my vibrato is kinda legendary lol. So, I'm SUPER ROUGH on my nails! My philosophy is, if I break it, I'll just fix it. So I typically go through my day not giving two thoughts to my nails. Having done my nails for going on two years. I'm pretty good at knowing which fingers are gonna be the ones to give me problems. My right and left thumbs, and my left middle are my two trouble nails. I know I'll be trying this product on my other nails soon enough. So if anything changes then I'll change this review(not likely). But as of right now, this product is a five out of five. It's exceeded my expectations. Oh and I also did do a clarity test when I first got this stuff but I didn't take any pics then. It is CLEAR! And just a quick tip to those who may not be used to using a thick B.IA.B.(builder in a bottle), swipe away as much product off the brush for the first coat but don't cure. Load the brush and then fill in the thickness on second pass. Oh and hold you finger upside down so that the product doesn't puddle at the sides. That's what I've found has worked for me.
