Have you considered that you are bumping a two year old thread referencing an expired ad, where the pics have not been updated in more than a year, and during the ad's life of almost 3 years the escort only received 3 reviews on Rentmen... I suspect this may not be the wisest choice.
Rasllan used to be Roslan: https://www.companyofmen.org/threads/411-on-roslan-nyc.148924/
Omar has been discussed before: https://www.companyofmen.org/threads/411-on-omar-nyc.145519/
Rammi also seems familiar.
Doesn't do much for me either, but I have learned to let it pass - don't like it, don't look. We all make choices that others disagree with. (I know I've made my fair share of bad choices!) I mean, there was a time when I wore boat shoes...
Discussed a number of times before here on the forum. Example:

Frequent name changer (we should create a watch list, honestly!). Would not repeat.
It really depends on the escort, how far they are being asked to travel (flying him in from Hong Kong; he will be tired), what your expectations are from the overnight and of course chemistry. It is almost always better to meet the individual first - have you seen the movie "The ghost and the darkness"? Never go into battle with an unproven rifle...
I choose to tip for good service. Whether it be incall or outcall. There are countries where tipping used to be frowned upon, but I have found that tipping has become way more acceptable in most service industries even overseas - I have never had a companion tell me that I over tipped (even in Europe and Asia). I do try to keep my tipping discreet and in line with what the local custom would expect - I moderate my tipping in Europe and Asia.
