I have hired 3 people in the last year for speed work, over $2k spent. Every single one of them failed at delivering a noticeably faster website. Each time I was told, that because we had so many customizations and apps on our Shopify theme that things couldn't get any better. I was tired of seeing our website take so long to load, especially our main collection pages and product pages. As a last ditch effort I tried SpeedBooster. I was floored by the noticeable jump in speed on those particular pages. Prior, it would take almost a full 30 seconds+ to load our reviews on our product pages. Now, it's nearly instant. The lazy loading helps tremendously as well. If you are hesitant, don't be! Douglas was the one to implement our changes and he was polite and efficient. Since we are always doing slight tweaks to our website with the theme/customizations, I will be hiring SpeedBooster again in the future to help clean up any mess left from our other developers. Definitely would recommend 5 Stars*****
