It looks pretty when first navigated. However, when you drill down to product details, the image alignment and description alignment are not in sync and thus overlaying on top of each other and the background image. It feels like a novice catalog / order system like you would see on AWS or 1and1.com
The latest issue is that when drilling down to further individual products, the browser just hangs. I just tried drilling down to Zeal Blades from the cascading menu and it just hangs at the load screen. The old site was just FASTER and more efficient. I'm 5 minutes in to waiting for the Zeal Blades page to load and it still hasn't completed. I would definitely say back to the drawing board.

Slow for me too and actually have to reboot after hanging up on it. For example. If I go to Main page then hover over Multi-rotors and click the Yuneec model it goes to that page fine but if I click the model on that page for more info the entire page just hangs up.
Not only that, once I exit the tab I'm trying to open it in I can't get anywhere else on the internet except Google until I do a reboot. I know that sounds strange and might not make sense but I can duplicate it time and time again.

The new site looks great. That is where the good stops. Site is very very slow. Takes about 15 sec to load the home page. Sometimes as much as 30 seconds. Searching brings up irrelevant results. Search results do not display correctly on iOS devices. I really hope they get this fixed. It will keep me from purchasing products from HeliDirect.com
