Hey there,
Sorry to hear about that, I've read extremely mixed reviews on the repiti-fogger and this seems to be one of the most common. For £55, I just couldn't find a reasonable exvuse to get myself to buy one, the only pro it had has easy set up. So I started to look online for alternatives.
Long story short, I ended up buying my own fogger, and it works perfectly. The actualy unit has that cheap that, if it ever broke, I could easily replace it for under 10$.

^ If you don't know how to build one yourself, I recommend that you read my thread, it's an easy tutorial for people like me, who had absolutely no idea how to do DIY stuff, to set one up.
There are only 3 steps (well, basically two) and it is 3/5 of the price of the reptifogger. My own costed me in all £21, I could have gotten it cheaper had I of bought the tubing in a different place, so hypothetically, it could have been £16-18
