Which DIY nail products are good?

I see a lot of people doing their own nails these days. What products do you buy?

I've been browsing through Dashing Diva and Ohora because they have so many pretty nail designs, but I'm curious if they last as long as they look.

I bought Dashing Diva Magic Press a while ago, but perhaps because I didn't properly remove the oil and moisture from my nails, it didn't last long

It kept falling off. I'm planning to buy one that sticks on like a sticker and then bakes, but there are different types.

There are so many that I don't know which one to buy.

For those of you who do it yourself, what brand do you buy?
