This Panasonic cleaning detergent is required for the shaver's cleaning system. It is expensive and not very pleasant to refill, but it seems to work effectively. Doesn't last quite as long as they say it will. The package arrived,well packed, the day after I ordered it. Very efficient service.
Item arrived in next morning's post. It was as described. The washing fluid has worked in the past so I can only think that it will work in the future. What more can one say about shaver washing fluid.
As described and a great service from this company.
