I have tried a number of top coats, and keep coming back to this. I used Orly's Won't Chip most recently, and think they should change the name to 'Will Chip Within Hours of Application'!.
This product dries nice and quickly, which is perfect for me as I'm so impatient! I did my nails on Wednesday and not a single chip or imperfection to date. As part of my job I type a fair bit, have my hands in and out of files, and at home I do the washing up a lot. I will definitely stick with this one, and the only niggle is that it does sometimes pick up the nail polish colour. Maybe that's my impatience and I need to leave the polish to dry a bit longer though!

PROS:
- dries really fast.
- it makes the nail color look smooth (when it was still new. now that i am more than halfway through the bottle, it is now thick and goopy and it ruins my manicure because it forms bubbles )

CONS:
- it dries really fast, too fast in my opinion. it dries while i am still applying it and i end up with bubbles. i live in the tropics though so it is really hot and humid here. that may be a big factor on why this is not working for me

i used this last night over an orly polish and i was literally in the bed. my nails dryed pretty quick and this morning no bubbles or smudging. my nails are high gloss and look almost wet. this product wasn't thick but it also wasn't liquidy. it didn't pick up color from my polish and as long as you use it quickly, like all drying polishes, it won't ruin your nail color. i'll pay close attention to how long i think this lasts and report back. i'm hoping for at least 5-7 days.

I used an orly nail dryer 10 hrs ago in high school and it worked awesome. I decided to give it another try recently and it is still awesome. I can put on a base coat and 3 coats of color and still have my nails dry and not have sheet marks in them. In add a coat to shine them back up after several days. If you do a base coat and 2 top coats, you do have to wait 30 mins or so before you are safe from sheet marks, but after 10 mins or so they are no longer tacky, so you don't have to be super careful, but you wouldn't want to start cleaning your house. It is verynshinny and I really like that as well. Won't go without this product ever again!

I LOVE LOVE LOVE this top coat. I thought Seche Vite was my favorite until I started having problems with it pulling my NEW manicure/polish back from the tips, like shrinking. So I ventured for a new "holy grail" top coat and came upon Orly In A Snap. I love this top coat. Works exactly the same as Seche Vite, except it does not smell quite as bad and I don't feel like I'm killing myself and it does NOT pull my polish back either. Also have not noticed cracking of my manicure after a few days. Only thing I wish that the bottle was a bit wider instead of long, as it can be tricky when the product starts to get lower in the bottle. As with any top coat, you may need a polish thinner after a bit of use, to keep it like new. Would buy this over and over again. Remember you will be able to breath in the same room too.

Thank god somebody has invented this stuff for impatient active people like me! I can hardly wait for my polish to dry and used to end up with a lovely square pattern of my bedsheets on my nailpolish the next morning because -after a long day- I just couldn't make myself wait 2 hours before going to bed.
This topcoat has solved this problem effortlessly. I apply a thin base coat, two thin (!) coats of nail polish and immediately afterwards this top coat. After 15 minutes everything is dry and hard. Really hard, so I don't have to be careful anymore. Problem solved :)

love this product! dries my nails fast and the cap makes it easy to open. buying this again for sure!

Dries fast, but my polish cracks after a day. Not chip...crack...like glass. But I understand certain topcoats work differently with different body chemistries. The best one for me is Seche Vite Dry Fast!

i found this in NZ in a country town store. it was $5 i think and i was like meh i'll try it out. Mine doesnt look like the picture but its called orly in a snap so i probably got old packaging.
this thing work a treat! after i do my nails i wait a few mins then i apply this and whoa do they dry my nails fast. I usualy going to bed after i do my nails so its not like im going to do house work or dishes after, so i cant comment on how durable my nails are after i my nails dry. However when i wake up my nails are still shiny and they havent smudged in my sleep.
Love how this thing makes my polish SUPER shiny. Im not going to say this thing make my colour chip less, honestly my nails always chip after 1-2nd day from just doing day to day activities. It also make my nails feel hard and thick :) the brush is good and this thing goes on so wonderfuly and easily! fab fab fab!
i have had my bottle for 6 months and it hasnt gone gluggy :) i would so purchase this again.

Okay, so I specifically logged back onto MakeupAlley JUST to talk about this product. I only come on when something is really something special and worth typing about. So here it is... This product I picked up by convenience, not because I knew anything about it... But this has led into a 4 year love affair! Not only does this preserve my nail polish for days/weeks/maybe months? (I haven't tried - I change polish so often, but I'd believe it) but it also provides a super shiny finish that compares to nail salons. It gives nails a thickness as well, much like acrylic nails would (if you're into that thing.) I personally vouch for this product, been using it for a while and have just recently ran out and have purchased two more bottles!
