I also have extra new and expensive version number ordered with the model number 981-000550 and 981-000257 was delivered. This is the old and slightly cheaper version that is still available on Amazon. Once bought at BLUE ICE and once at RB deals. Goods I sent back in both cases. As you can read here, other customers have had the same experiences and it seems nothing has changed. Can this still be a mistake? It is very likely that these traders try their old stock to the unsuspecting customers - which this difference in the model numbers do not realize the actual selling
