I don't like them. Too big, and cordy Casio should reveive the discontinued HDC600, and make a budget, standard, amd premium version out of it. There are way to few anadigis, and way too few watches for small writs.
I also prefer smaller-sized watches, and for this reason, I had to do some testing to convince myself. Initially, I bought the GMD-S5600-7ER model, which is slightly smaller, but in the end, I opted for the GW-M5610U-1BER. The difference in size is imperceptible, but it has several additional functions. I recommend trying it out in a store and deciding afterward.
