Pascal Berger, maker of the Octopus pulling system, recently put out a statement on Facebook warning that Czech company SOPRAS APNEA was marketing a low-quality copy of his design.
The way to spot these copies is to note that they don’t have the Octopus logo engraved in the lateral structures, their SOPRAS logo is printed on the aluminum arm and the structure is made from a much cheaper plastic, which might break after some months of use, according to Berger.
Berger says his version uses an extremely strong thermo-polyamide charged with 40% fiberglass and UV protection.
“As the designer of this original product launched 3 years ago on a crowdfunding [campaign], if you spot these copies in any shop/center would be nice to drop me a line at email@example.com.”
