i have used this for a long time. the pros to me are: can be applied over wet polish for faster drying; very shiny finish; reasonable price. i would have given this a five but i recently discovered essie's good to go and like it much better as a top coat, but i will continue to have sh megashine in my collection because i esp. love how it perks up a pedicure - i can apply it every few days and my toenails look great for a couple weeks, even in summer. funny i didn't even realize that the silver bottle bugged me until reading the review below, but, yeah - can't tell how much is left.

A decent top coat. It does add a lot of shine, but only for two to three days; and protects against chips moderately well, about five days chip-free (and at day three I applied another layer of top coat). The formula is thick and takes a little longer to dry that most top coats, but it is not unmanageably goopy. It strips off some of the colored polish. I do not recommend using this alone or only over a base coat for clear nails, it peels off for some weird reason. This was nothing fantastic and I’ll pick a different top coat next time.

I really hate this stuff. It does give a nice shine (hence the 2 lippies), but it also pools in the "gutters" on the edges of my nails and makes a weird white mess there . . . and then lifts at the edges and peels off. That's plenty to make me toss it, but while I'm complaiining--also not in love with the opaque silver bottle that makes it very difficult to tell how much is left. I've used other Sally Hansen top coats that were great, so I don't know what they did wrong with this one. Ick.

I have tried using this several ways before I just had to give up on it. I have used it on bare nails, over polish, and just over a base. No matter what I did, it peeled off within one day! It totally reminded me of those play nail polishes I used to have as a child because it just peeled off in one complete piece.

The only reason I gave this product 1 star instead of 0 is because it does produce a very nice super shiny shine. I don't have any problem with the packaging or the price. But if it peels off within a day what is the point?

I have been using this product for years and will continue to do so. The big attraction for me is the quick drying. This, to me, is comparable to Poshe Top Coat only much, much less expensive. I would not be surprised to learn that Poshe makes this for Sally Hansen, to tell you the truth. It is THAT good. Lovely shine, super-fast drying time, lasting manicure. What more could you ask for? This is my HG topcoat.

This is my HG topcoat! I've been using it for years and love the protection and shine it provides now just as much as I did when I first tried it (a rarity among my cosmetics, I assure you). I usually use this on my toes -- I first apply Essie's ridge-filling basecoat, use an OPI or Essie color (2 coats), and then top it off w/Mega Shine. It keeps my color fresh and chip-free for 2-3 weeks easily, even during the summer months when my piggies are most exposed! I like that it dries quickly and helps make at-home pedicures look like they were done at a salon. I know I sound like a crazy lady from an infomercial in how I rave about this product, but it truly is great. I don't know why the mags don't promote it more -- I'll continue buying this as long as Sally Hansen continues making it!

This is a great top coat. I have had it on my toes for over a month and my pedicure still looks great - and I have even been to the beach! It also dries really fast which is great.

It removes easily with regular non-accetone polish remover. This is the top coat I will keep going back to. (I have not tried a manicure with this top coat yet)

This is very good. I will try another one from Sally Hansen just for a change, but I would definitely come back to this. Great shine.

By far the best top coat I've ever used. I've been buying and using this over and over for at least 5 years, and I will never be without it. It dries super fast, even drying the coats of nail color underneath, and the shine is incredible. Definitely a bargain at the price.

I was very disappointed with this product, it made my nail polish peel after 3 days, the whole lot would peel off I one big chunk. I've given it 2 lippes as it did make my nails very shiny.
