Warranty Bosch
In addition to the statutory warranty (2 years), the manufacturer’s guarantee applies. As an authorised dealer, we help you directly with any warranty claim.
New
This item is new and unused – not B-stock and not a demo unit. You can recognise B-stock in our shop by the yellow condition pill showing its condition.
Best online price
Buying direct is cheaper for you
Price comparison portals and search engines charge high fees on every purchase – often over 20% of the selling price. These costs are always passed on to customers. We do things differently: instead of spending advertising budgets on large platforms, we invest in fair prices, BROpoints, gifts and exclusive best-price deals you'll only find directly with us. No middlemen. No markups. Direct for you.
