We have 100 units available and also 2 transport flightcases.
The audioguides are very easy to use. You just have to select a number and push the play button.
The audioguides aslo can be used outdoor.
Their autonomy is really amazing: with two regular AA batteries they can stand 120 days (regular use).
We can put the audiofiles on the devices in preproduction (we have the specific software to do this).
We have a UPS account which makes it possible to sent it to other countries within EU.
If you have a VAT-number we can do "intracom invoicing" so you don't have to pay VAT.
