Ordered for my husband who is a repeater of this clock. Works as expected.Screw CHRONOS GX CHESS CLOCKS. I've spent over three hours trying to reset this clock and can not. While the left side display shows 30 minutes with the game-over dot, the right hand side shows 30 minutes with the game-over dot and a move counter. I could not clear either side. I took the digital clock and smashed in onto the floor out of total frustration. When it comes to chess clocks just stick to analog clocks. Are you listening USCF as I spent over $110 on one of those digital clocks.Superb chess clock! The user interface is not for everyone (or most even, only appeals to the geek). Nonetheless, this is the best chess clock I've ever had.GoodI've had the original chronos for about 20 years. I recently lost it by forgetting it in a coffee shop. I didn't realize how attached to it I am. I even lost sleep and checked local pawn shops. This happened during a period when chronos was not making clocks and Ebay was selling used for about $300. And then I found it in a storage room in the coffee shop. I was so shaken that when this new chronos became available I snatched one up as a backup, it does require a small effort to get used to controls but so do all digital clocks. In my opinion this is the best chess clock available. If someone still thinks analog clocks are the way to go, perhaps their best playing is behind them.
