We can give no surety, guarantee or warantee for counterfit (plagiarised) OTIUM soft-close sliding door dampers or copies there of.
Please ensure that you have a proven original.
You can do so by checking the serial and batch numbers printed
on the side of the damper.
A patent number and the brand name OTIUM are also moulded into the polymer housing. If both of these markings are absent, you certainly have been sold a copy.
If so, please report this to the manufacturer.
