Great search engine but misleading advertising. They claim you get 5 free searches per day but after a while it won't let you search for free and you are forced to get the premium version and if you have the funds is well worth it but they shouldn't lie to get you to pay for it. No complains besides that.
I've been using You.com for around 4 months. I tested the Pro version briefly, but reverted to the Free one since I discovered a more cost-effective tool with improved UI and UX. It's quite good, particularly the Chrome Extension, which proves to be very useful.
