They do ship to Bahrain but i'm not sure about what you mean "Reliably" however, what i can do is tell you about my 1st and only experience (so far), i bought a 5.25" internal card reader for my PC from them and what i have to say or i have noticed is:
(a) They sent the item in it's original box ONLY, it just arrived as it is so there were no protection packaging for the cases of falling or bumping or poor handling (Definitely a mistake from them), it was only put in the courier/shipper plastic bag!
(b) The box itself had signs of wear, tears and bumps (courier's fault) even though they were relatively minor however, luckily the item inside was in perfect brand new condition.
(c) The shipping of the item was actually slow considering that it's from a neighboring country (Emirates), it took around 20 days to arrive from a nearby country while items from Amazon take 10-14 days to arrive from the US!

Would i buy from them again in the near future? I probably would, but i hope this kind of negligence and these mistakes never happen again because it won't be tolerated. I hope i helped :)
