Diecast Model Centre review for Rontar Ad Exchange: Free Ads

Was really expecting to see some good results from this app, but it's turned out to be a terrible ROI, just 2 clicks (which didn't lead to conversions) from £50 spent - something is wrong somewhere. Also not pleased that after taking my initial £25, they took another £30 off me even though there was enough left in my account. Pulled the plug before I lose any more money.
