Has anyone else tried Ruma Travel?

I’ve recently been using a new site called Ruma Travel and thought it was worth sharing with the group. It seems to be one of the only sites that instantly compares cash fares with reward-flight options, including flights you could book using points transferred from Amex, which I found really helpful when booking my recent trip to the US.

You can also add your different loyalty programmes and points balances to a wallet, so the results are based on the points you actually have. For example, if you collect Amex Membership Rewards points, you can add the airline programmes you transfer them to and compare relevant reward options alongside the cash price.

Has anyone else used it? I’d be interested to hear your thoughts, or whether you use any similar websites for comparing Amex points and cash fares.
