I have had 2 frost free and love them cos they do keep the bad old frost away.
Mine are BEKO - unfortunately you wouldn't believe it the 2 of them) - they leak at the back of the "fridge" bit. I clean them all the time ie the little hole but no the water still comes in. So I just put a clean tea towel at the little hole which sucks up the water and live with it.
My cousin bought a BEKO last year and never has had a problem. I still would buy frost free - who wants to go back to pots of hot water, hot hairdryers. Not me.
