I have been using WP-Compress and have been satisfied with its performance. So once it came on Appsumo, it was an easy decision to go for the highest stack.

Initially I had problem with understanding the credit system, but then when I started using it was a fairly simple system.

I have been easily getting close 60-70% better performance post optimization with WP-Compress.

But beyond all these the clincher for me is the super responsive support and the customer focus of the support. Everytime I have reached out to them, they have overwhelmed with their solution which has always been above expectations. This is my primary reason to rely on them as they always have customer interest in their mind.

I wish I can write more technical review, but I buy my products based on the reliability of the team and the help they extend in making their customer successful. I would give full marks for them.
