Unused as it arrive too late for my trip (delivery issue, no fault of Base camp), so will try to update when tried.
But the service from Hollie at Base Camp was 1st class as was the price, have got my eye on a few more of their item, just saving the pennies up :-). Would recommend Base Camp for price and service
