I regularly visit the site and check sales in progress. I haven't bid on the site for many years, far to difficult to make a good profit on UK names at the moment. The site has a good reputation going back many years. If your selling don't expect any decent interest unless the domain has wide appeal. Generally, Niche domains won't appeal to this audience.
Every now and then you'll see a good sale in the UK£5,000 plus range. But in general names sell (if at all) at around £50 plus, (the starting price)
For example Dentalcover in co.uk recently sold for £321($400) yet it's a hot topic for both getting on to a NHS service (almost impossible) and for upselling private care
