Thunder Page Speed Optimizer

The overall experience was very good I really appreciated the work which the developers has done and also the support team I quite good. Highly recommended app for speed optimization.

Thank You

Nice App!
The best service ever.
They have manually optimized my website, and got a significant improvement.
GOOOOOD JOB guys!

Just very Good! The use of the App was just fantastic and really easy to use. It made my site way much better on Mobile (desktop was also better). The Support answers all Questions and is very acceptable and dosent hesitate for anything.

Definitely over a 4.5 Star Review!

The apps works great and George has been so helpful with installing and improving the app on our website!

Quick support! Had an issue with app not loading and it was reaolved within 30 minutes or so. Great reaponse!

The app is great and the developer is very willing to help you fix issues with your store speed.

I can’t open the operation page all the time, and there is no reply to the email contact. There is no reply after contacting for three times in a row. Extremely bad service

The speed score of my store was below 30 and after installing and waiting to see some results, now the speed is 54, I can honestly say that this app is worth it, and I highly recommend it to anyone looking for an app like this one.

Wow, I've used a lot of apps to speed up my store. Half of them seem to do the opposite. Thunder is really very good. Had a little glitch in setup and Georgi from the support was fast, efficient and friendly. 5 stars all round from me :)

Critical css, image resize not working on my website. Not sure if prefetching works. Within the code of loading bar and therefor sort of hidden, a link to https://www.w3.org/ creates "the largest contentful element" with error, read by website speed anaylizers also as an error, somehow registers for a higher speed. The only true benefit using this app was compressing the css file and nothing more.
