Thi is a very good product.
I only use OPI for more than 5 year, they are so good.
the start to finish is very efficient. i use it as a base coat, and as a top coat, and i swear, my nailpolish lasts for at leat more than one week, it shine a lot. OPI is for me one of the best nail polish treatments for nails

I love all OPI nail products! Absolutely the holy grail when it comes to nails. The OPI start to finish base coat, top coat & strengthener is an all in one product that rocks! The drying time is fast & efficient like most OPI polish. It is an amazing base coat protecting nails from stains and is formaldehyde-free helping to prevent fraying and breaking. All nail polish colors stick to it very well and it leaves a beautiful finish as a top coat. All around must have!

I wanted to get a base/top coat combo so I found this online and got it for about 7.50 CDN including shipping - NIB. I think it retails for more than that, but about 5 bucks. Especially in Canada. And to be honest I've never seen this product in stores, so I was interested.

It applies nicely and makes a smooth layer to put polish on top. The percieved quality of the product is high for me so I really want to like it. I'm trying to be pragmatic about it. We'll see how it performs. I wound up being dissapointed in my Rimmel Base/Top Coat when I wore it for more than a day. It didn't make my polish last longer at all, but it seemed to make my polish dry a bit quicker, or maybe it's just me.

I really liked the way this formula applied, very easy and neat. I really like OPI brushes. The finish on my polish is really nice so we'll see how it wears. I'll try to update.

I would suggest that more people start EBaying polish and nail products. You can get some amazing deals and some rare polish shades. It's really worth it.
