yeah there is a guarantee on their website.....
In addition to our 30-day unconditional satisfaction guarantee, Monsoon Products Co. guarantees for a period of one year that the magnetic car bra will not damage your paint through oxidation caused by trapped moisture, or abrasion caused by flutter or flapping. The guarantee does not cover damage caused by intentional misuse or failing to follow the instructions on installation, maintenance and care.
i asked him about maintenance.. he said once a month to remove it and wipe down with water under the bra and that was it
i have a good feeling about this... and even if it doesnt work out like i hope... the amazing customer service this guy offers is worth the money i spent on the bra... ive sent him about 6 emails... including a couple at 10pm or later... i dont think ive gone more than 4 hours without getting a response from him.. i placed my order, within 3 hours of sending my payment, he emailed back saying to expect the bra in 3-4 days
