I thought that this thread might be helpful to those looking for size comparisons on some of the RDAs that are available for online purchase. I know that not everyone can see these items first hand or in a shop, so in this thread I would like members to post size comparison shots of the rba/RDAs that they own. Thanks very much, and I hope that this helps someone!
Here are the ones that I have, all are authentic:
