Upon loading I get this:

Configuring the app doesn't work on mobile devices, please use a Desktop PC.
However stay calm, the Mega Menus do work on your website for mobile devices.

>>>Is this a bad joke? What, are you stuck in 2009? :(

Great app to cope with Shopify simplistic way of building menus. I strongly recommend it.

Can I give you 10 stars? This app is actually really great. Given the options that can be done to really provide the UE in a positive way, it is truly a great app. I recommend that if you need robust menus for your store or site, this is the app to pick first!

I had it installed and i deleted it. The next thing i saw was all my menu disappear .

Mega Menu gives you something which Shopify simply will not give you: Professional looking and easy to customize menu.
If you have a lot collections in your store it is frustrating and almost impossible to organize them, keeping it simple, clear and easy for your customers to navigete...well it was :) With Mega menu we do not have this problems anymore.
And it is blending in our theme nicely.

I would also like to mention great customer service without whom even great app is not worth to buy and use.

Great job guys!

Roxana Dascalescu was amazing . I had issues with the menu when i changed my theme but she was supportive from beginning till the end and the menu works perfectly fine. Thank you Recommended menu for everyone, the free features favors small stores. It's just an app for everyone!

Great App. Extremely useful. Customer support is very friendly and helpful! Awesome experience.

Amazing app. Clean and easy to use. Perfect for those looking to make your menu experience more professional.

great app. I think it has made my store much more user friendly. App is easy to use. I hope our friends at Buddha, make the column alignment configurable on future releases...then it will be even better than it already is. :-)

works well. I'm on the free version, and so far it's worked for what I need.
