I've got some.
They're great when they work, luckily it's been no trouble when i've returned them twice.
The problems i've encountered are that there is trouble with the ink in the display so the number doesn't show up well enough to read. This was happening more often in winter, I took them back and I was given a fresh set.
A few weeks ago I had a fish that I wanted to weigh, I left the fish in the net resting in the water and tried to get the scales zeroed, sadly they zeroed a little too well! 0lb 0oz was the only weight that was registered even when I took the wet sling off the hook (usually it will read -8oz or however much the sling weighed). I rested my finger on the hook to see if it would read out a weight and it didn't. I had to ask another angler to borrow his scales. The scales work again and it's only happened the once but was very frustrating, I've taken to carrying my old weighmasters as well just incase.
Also, when you hold the button down to turn it off, it can sometimes come back on again. It's worth checking it's off before you put it back in bag. The flip side to this problem is that should you put the scales back in your bag and they wake up, after a little while they will turn themselves off.
I can't remember how much I payed for them but I'd give them a 7/10. They're really good scales when they behave. Mind you, I have incredibly bad luck with phones and computers, so perhaps I can add electronic scales to the list!
