original poster back 6 months later,
Purchased the Bendi, pretty dissapointed, the reccomended isle widths are too narrow for practical use, taking 3 to 4 times as long as a reach truck per pick and getting alot more product damage.
The machine is poorly designed and the manufacturer does not have solutions for design faults.
Machine has spent 3 days out of service during first 6 months of service.
In hindsight I should have stayed with reach trucks and lower density storage.
