PM sent. Its a direct email contact so I will not post on a public forum. I have no business or personal relationship with the supplier, apart from buying at very good prices.Btw, where is the site that sells Puck for 110 EUR..?

single button computers are a colossal pain to deal with btw, I would highly recommend against them.
I hear this all the time but don't hear the specific issue with the discussed computer.
I use the Puck and the only time I find the single button an issue is in the Dive Log, if you go past a dive you need to cycle through all the logged dives, or wait for it to time-out back to main screen. At worst 30 odd button presses. All the other functions as very straight forward.
If you look at the Zoop not only does it have multi buttons (and you need to remember which does what) it also has multi-button presses. I go on a lot of boats the biggest pain computers are the Zoops.
Just my 2cents
