I've just had my coil changed today and I too was extremely nervous having read such a bad review on this site.
I can not fault the doctor and the staff who assisted him they all made me feel at ease, it was dignified and everything was explained to me along the way.
I would highly recommend anyone having a coil fitted and definitely recommend this place to have it done.
I was not rushed off the bed afterwards either in fact the lovely young nurse made me a sweet cup of tea and I was given as much time as I needed.
Thank you to the staff there including reception- see you in 5 years (except for when I come for my 6 week check).
