You get what you pay for
Lam Woon is a really nice guy from his emails, he responds promptly and he did bring my site speeds up for a while and I found him completely trustworthy. However..there is a cost to the service. My site now requires daily maintenance and actually I can't replicate his page loading speeds even using a server in the same country as mine on GT Metrix any more. In addition, the site has started to crash sometimes because of memory issues. It was $49 well spent to show that a shortcut wasn't going to sort out my issues (I have a very image heavy site), so I am now in discussions with a more expensive firm to get things sorted out properly. Not right for my needs.
