After about ten years the original unit was using up cartridges very quickly and sometimes leaking. With the replacement unit the usage is back to normal. Well worth the cost, which was much less than Amazon.
Bought to replace a broken original, works as expected. Only difference is, it has a gloss finish instead of a matt.
The shaver station really does clean the razor to give a better shave than you could get by cleaning it manually. Simple & quick to use.
