I ordered 3 of these tamping machines, which are now almost 1 year in use. After one of these machines did not work and they somewhat disassembled, I realized that the shaft connection of the main lever is screwed to the housing, is miraculously of the cheapest plastic and was broken. This machine is its mechanics down to this part of metal. After consultation with the seller "Nick & Ben" (reaction time when a customer purchases at that time more than poor), is this a wearing part and therefore not covered by the warranty. What good is the most stable machine when a component (intentionally) consists of the simplest plastic! Impudence!
