I have been using Internet cheapies (the v early test 10 miu ones) but have read a few times on here that they are not very reliable and that FRER is more reliable. I was under the impression the 10miu was the most sensitive you can buy, so wondering if anyone knows how the FRER is better?
Have had faint positives for a few days on the cheapies but wondering whether to invest in FRER to get something more definite?!
Thanks ladies x
