Product good, delivery good
Firstly the delivery was fast and the transaction simple. Thanks. The Bosch is well built, has the power to tackle some thick growth and you can get a second battery 8amp by redemption free. Happy I selected the bundle and the dealership.
Great company, great support, great product.
As with all of the rosewood marbles tools, great quality. Now I just need to stop the students from damaging them.
No problem with the whole transaction
