What can I Improve?

What exactly are you asking?
Do you want more visitors or more purchases?

Overall I think your site is easy on the eyes and not cluttered. I will just comment on some design improvements you can adjust. I see that the image transitions are too fast, it does not give ample time for the visitor to read it. Also the paragraphs are indented, maybe it is your design preference but I think it will look better if it is aligned to the header. Regarding that, try to tag the headers as H2 or H3 perhaps or put it on bold since it is hard to distinguish it on my perspective.

I agree, uniformity is advised for the content. I love how you have an option to categorize the products by color, size, and Bluetooth. I tried to add products to cart and it seemed to respond fast,. It is also great that you have an option for support on every page. I think it's all good so far very direct and easy to navigate.

What I noticed is that you have an affiliate program. This is a great way to boost up your sales and help others through commission based earning. The images load fast, you have an option to connect to social networks, relevant information can be easily found, a live chat support, options for product review. I think it is a great site, simple and straight to the point.

Layout is pretty interesting and has a tendency to attract a lot of interested buyers. The only thing which I found kind of odd was that once you scroll down the page you end up finding a lot of information squished together regarding the specs of the device. I think you should replace that text base description with some visual content so that your site visitors can feel that tech vibe at the first glance. These were my two cents. Overall , your site structure is well made. Keep it up and I hope you succeed.

Cheers

1. Gold color in the cart top right is bad shade. Please change that color to something more refreshing and less "shitty"...pun intended.

2. Fix your typography (font weight). A lot of the fonts on the page is too small and hard to read. The thin borders around the product could have a little more punch. You'll have to play a lot with CSS to get things to how they should be. Right now the site looks very generic because of the fonts alone. The price could probably bigger if you want to highlight the sale effect. Fonts in footer could be cleaned up, too. Even the fonts in the logo slogan is hard to read.

3. Get rid of the stars. Unless you have tons of great reviews to back that up, don't show/use it.

4. Put a hoverboard or something else, an "R"? in your favicon instead of a shopping cart.

5. The chat function could be personalized better. You probably might not even need that.

6. Kind of weird to show CHECKOUT in top right. You probably need only "Shopping Cart".

7. Might be good to have a "FREE SHIPPING" message bar at the very top of the website.

Overall, I would say it feels extremely generic. Like you bought a template and swapped out some images and not much else. It needs way more character to really feel professional and polished. I could say a lot more but you should start here.
