Product and your services are absolutely fine.
I have some observations regarding your website.
1. While placing order, after the payment the site is automatically getting logged out. And, if I log in again, the order details are not visible instantly, it is taking time to show orders.
2. I am not able proceed from the cart option.
3. Website usability and visual appearance can be more convenient and simple.
I suggest you to please concentrate on these, as many users will leave the site when the user experience is bad.
