I have tried the brow wiz and they're both good. The brow definer is thicker so the application is much faster and smoother. To be honest I was scared mine would break once arrived, but luckily it didn't. The negative point is that the shape doesn't stay like that. The edges don't stay sharp. And yes the product runs out quickly, but I'm happy Cult Beauty offers free shipping on Anastasia this month. So I'll definitely reorder!

I have never used the wiz, so I can't compare, but I don't really want to, since I think the shape of this is much better for filling in the brows. My problem area on the brows is the top of the arch and it takes just one simple glide to fill it in with the side of the definer. It just sells to me. The formula could be a little bit dryer to make it perfect, it glides on nicely, but I think it might smudge a bit too easily if you're not careful. If I could I'd give it a 4.5 stars, since I can't - I'll do 5.

I usually love ABH products but this one was a no go for me, I've used Brow Wiz before trying out this new product that I was really excited about despite the love hate reviews I've seen. I really did want to try this out. The pencil on the Definer is much more harsher compared to the Brow Wiz and I couldn't get the hang of it. It also was broken a few days after I got it, really disappointed.

This is still a great product but it's not as good as the brow wiz. It took a bit of getting used to, but all new products do. I will definitely always have one and buy the definer again but I think the formula and precision of the wiz is much better. I find that the product tends to wear off more using the definer, but still worth buying.

Was really excited about this. It goes on well and I love using it, however it is not durable. It was broke when I got it, so ran out really quickly. Little disappointed!
