I like to use nitrogen for e-commerce websites as it has good support for magento. Also it has integration with third party systems such as paypal etc. So i can easily do all my payment gateways for my clients. I dislike the fact that there are some issues still with loading time while browsing on mobile devices. It feels sometimes sluggish. If you have a website powered by Magento then nitrogen is definitely worth a try. For me, nitrogen is one of the best Magento plugins in terms of providing an excellent user experience, great customer service and a very strong technical team. From payments to order management, from shipping to managing inventory, nitrogen helps us deliver amazing outcomes to our customers on a daily basis. We have been able to deliver an amazing user interface with no lag time or slow loading times for our users in New Zealand who are viewing products from other countries such as Australia! I would definitely recommend it - there's nothing about nitro which we dislike so far; everything has helped us improve how customers interact online at this point (even if some things can be improved).
