As I said, I had the DM one too. I'm not hyped on the brand or anything, I was very sceptic when I bought the 303. Yes, maybe it's odd shape fits me well thats why it's soo good. But it's accuracy (3360) and click feel is great. I tried quite a few mice after I sold it but even among Logitech this spring tension system on the main buttons worked best on the 303. I tried the G403, G Pro, G102 (and many other brand) and now I have a G603. Luckily I found a guy who sold me two 303s. So I'm stocked up and gonna' take care of them.
