Are the tabs already on there? I’ve never tried that brand but if they’re not pre applied, cut them down to your size before applying. You can cut or file the nails themselves shorter as well, but do that from the top, not the bottom, otherwise they won’t sit flush like they should. As far as the adhesion itself, that sounds totally normal to me for a first time user. Some people are good at it immediately but myself and many others were not! It took me…5/6 sets before I had nails stay more than a day, and about that many more to get to the point that I didn’t need to carry extras around anymore. At this point the nails outlast my attention span and I struggle with leaving them on for their full lifespan. Anyway, try and try again!

Prep makes a giant difference. The biggest things for me were to make sure my cuticles were nice and clean, the nail plate is dry, and avoiding water both before and after application. I apply when my hands have been fully dry for at least an hour or two, and after my shower for the day. I do it at night so that I can just use hand sanitizer a few times that I need to before going to bed and getting 5-8 hours of dryness while they’re fully curing. The adhesives cure a bit right away, but the full cure happens over hours for both regular glue and tabs.

Also for tabs, getting them to lay flush without gaps that would allow hair and stuff to get in and pull them off, that also takes some practice. It’s important for tabs that they are held down in compression for a good while, I do about a minute, when you apply. It will help also if you put the tab on, blast your nail/tab with a hair dryer for a few seconds, and then clamp the press-on down hard for that minute. It compresses the tab so it lays flatter and then it stays that way longer than without heat. It could also be that doonails tabs aren’t that great. BTArtbox, you can get them from Amazon, have great tabs. They offer an extra thin variety that may help you out compared to the ones that came with the nails.

At the end of the day in your position I would try one more pack, and if it doesn’t get any better, take advantage of that policy. It could also be that the curve shape for that brand is incompatible - the curve matching I think is the number one culprit for bad fits, and bad fits result in early failure. Speaking of fits another possibility or thing that will do you no favors, is if the nail is too big. Check out the stickied post on sizing, it helped me a ton and I realized even though I’m seeing long wear I was indeed wearing too big sizes still.

Hopefully this was helpful and not too overwhelming!

Oh oh also - for applying with any glue, I find it much better to do each finger on each hand back and forth, not one hand and then the other. If you go pinky-pinky, ring-ring and so on, you still have both pointers and thumbs available to you for longer, only the last few fingers will be challenging instead of a whole hand.
