Going to Buy this Bluetooth!?

HI folks im going to buy this SPP based Bluetooth module , i wanted to just know if in case i may be loosing on some fact about this >> Probots - Largest DIY Electronics, Robotics & Engineering Parts Buy Online Store Buy Online India that i shortlisted to buy, i have also eyed the RN-42 module and these both run on 3v3 power , can you guys just have a look on its Datasheet? and may remind me of something I'm not able to see.

Datasheet >> http://probots.co.in/Datasheets/AUBTM-20.pdf

i dont see anything wrong with it; just another MCU Bluetooth controller. ive used the RN42 with great success here: Digitalduino: Arduino RN-42 Bluetooth Module setup should be pretty similar...

Thanks SirBow
