From the reviews I have seen pal I would not bother. It leaks all over the shop. Cant see todds review though above as the internet at work has the speed of a sloth.
Ive had two now and now have a refund on its way. I can assure you that they leaked in any configuration I tried (from the button end). They were investigated by the vendor and replaced then refunded no quibble. They come in blister packs and so can't be individually checked. The first also had a short thread to the body which meant it came away in less than half a turn. The second was better but still leaked. And I had the nozzle cover off when I refilledNo, it doesn't leak all over the shop.
Simple reason for the ones you see leaking, pressure related, folk fill it up and screw the cap back on without taking the nozzle cover off, pressure build up occurs and leaks happen.
Screw cap back on and leave nozzle cover off and you will have zero leaks, common sense really
