Used Agoda to book rooms in BKK 2 times and CNX 2 times. Flowless every time. Once in 2008, I booked a hotel in lower Sukhumvit and I woke up with bug bites. Touched base with Agoda and they canceled my reservation and faxed me a confirmation to another hotel while I was the online chat with them.^ The last hotel I booked I got partial credit using my points. No problem posting my reviews positive or negative. Very pleased overall.
Will use them again for next years trip CNX BKK KUL BKK.
