As a result of using Ambipur :thumbs down , i broke both the central AC vent fins (rs. 1235) in april and the right side AC fins (rs. 292) last month. After much negotiations, i was fortunate to get them replaced under warranty stating poor quality of plastics used for AC vents. SA have warned me :firey in writing on the invoice to avoid using perfumes which are hook'd to the ac vents and no warranty will be offered to broken fins as a result of this.
