Important info before-from: Petra Electric is one of WMF and a broken lever is not a warranty case !!!
The stiff locking lever is widely known. This is now terminated after 2.5 years. Spare parts are indeed available (for the devices to be repaired by the manufacturer), but are no longer shipped. In the past this was available at 6.99 and the exchange was done in a few minutes. The "solution" is for the producer that device to send in unfree and, for 55 - to let raparieren. The hotline reacts with the theme subliminally irritable and aggressive - no wonder there probably call daily stinksaure customers.
My question is whether it is their seriousness, that I should throw away an otherwise technically and optically perfect device for a 0.15 cent spare parts and that can be neither in the interest of Pertra Electric, the environment, even the customers well, has been extensively answered: "there is not a spare part, all I can tell you."
Thus, from a German quality product, unfortunately, a single-use, disposable or device - at the present time absolutely incredible !!
Conclusion: apparently the manufacturer has failed to understand that you can only assert itself as a German manufacturer on the market, if one has a reasonable service. I buy at least no more units of Petra Electric or WMF!
