I've been a member of UC for 3 years and I can tell you that there have been some changes as follows:
1. Dating Type change - they removed the number system which showed you what the girl expected for her "room" fee as it was too much like escorting "D" class was the one.
2. They changed "E" class to marriage minded when in the past it used to be Straight Up escorting - so I think this hurts the girls in this level unless they are really serious about finding a potential marriage partner
3. They made the men change profile names to fake names.
4. There used to be a feedback system for the girls to comment on the guys, but guys don't have access so I never saw it.
5. Recently - last year - the number of D class has dropped while B and C have increased - which means more dates or "chemistry" if there is a chance for intimate encounter.
6. Seems the quality level of girls has reduced as well - just my opinion.
7. I was hard sold to upgrade to the Black Class for 200.000JPY and was told all the benefits, but to be honest, I can no see the value and return for this other than just feeling special and UC providing some special stuff like concierge and a private bar you can go to during the day to hang with free drinks
8. I've been on a few dates... over the past 3 years - some great and some terrible... after paying a setting fee, you need to pay for the evening - which is expected and not an issue, you need to pay the girl a transportation fee from 5,000 - 10,000JPY but there is no indication on what it is. Would be nice to know this in advance. I had one date flake out in Osaka - because it was raining... They told me they cancelled her membership after that.
All in all, I would say I've had an overall good experience, but the staff changes are continual and you have to get re-introduced each time... Tells me there is a management issue with the higher than expected turnover in their International Division.
I've made some suggestions to them to help improve the service but not sure they will be implemented. For example, if the girl says she can speak English regardless of level, then have a English video of her and English profile
If the girl has kanji characters for her name it means she is not foreigner friendly told by a staff member to me.
I haven't had much success on SA as well...
So if you are looking for a SB arrangement on UC I think you have a little bit better chance since they have been screened, but to be honest not sure how well that would help.
Their video's are shot the first visit by the girl, I suggested that they call them back so the girl is not so nervous.. I mean she is there to sign up and they say we shoot a video now, so you can tell that some are really nervous on this which is not a good representation of the girl IMO.
For the girl, she has no idea what the guy she is meeting looks like so it's a bit of a gamble on her part as well.
I think the photo's they take could be improved dramatically, lots of bad lighting or White outfit with white background - hard to see clearly... looks a bit amateurish.
Hope the above helps... If you have a crazy schedule and it's important to arrange a date when you are free, then this is a great service - providing the girl doesn't cancel or request a reschedule.
The Also have some meet and greet events but at 50,000JPY I think they are a little steep, but you can get many girls contact details so it saves setting fees - at least that is the appeal of this.
