Five or more years ago, Spectra sent out a batch of pickle that was not compatible with the plastics used in the construction and there were many failures. To their credit, Spectra repaired and replaced all damaged units without questions even for non-original purchasers (that included me). Now I won't use anything but Spectra branded pickle but since we (only) pickle once or twice a year a cost of a few pounds a pot really isn't worth the risk.

I am very happy with our Spectra and would add that a battery watermaker is hugely more flexible in use than a mains-driven one.
