It is a really good top coat. It has a square silicone brush. I love this type of brush - it just feels great to work with and spreads wide to cover a big area. I do however have to load the brush with a lot of polish otherwise it can drag on the colour but if you have enough it just glides beautifully. I have tried a lot of top coats and they are not all created equal. This one really stands out of the bunch simply because the finish is super glossy and glass-like. Looks gorgeous on top of cream or jelly polishes as it adds brightness and depth. The drying time is nothing like Seche Vite but I wouldn't say it is slow. I really recommend this product!
