This was delivered next working day...I fitted the system myself and within 2 weeks has cured our condensation problems.. Damp areas on walls and windows have gone, internal doors fit better again, laminate flooring had become mousey when you walked on it, now back to normal. Also air quality is much better, stale food smells do not linger..We have an open plan living area so this is really helpful....In fact It is only when you have removed the issues that you realise how good this system is...Great value for money too...I highly recommend this....
