I have that one. My only complaint is that I doubt if the pressure gauge is very accurate. Even the one in the photo isn't reading zero.
I use the kegland Blow tie, I've got both analog and digital versions plus the version without a gauge.
I’ve got a couple of spundy’s and one of the kegland’s, the spundy is far smaller but in terms of their performance there’s no real difference. You do have to fiddle with them for the first 2 - 3 days to get the right PSI to settle. I’m brewing IPAs mainly and go for 10 PSI which also happens to be the same as what I used to set my kegs to when carbonating. I
The digital version is MUCH more accurate than the analogue one. Even by virtue of the fact that the dial is so small, it's impossible to read accurately. Even kegland say it's no better than 10% accurate.
Ok, but does it matter? I simply check if there is enough pressure during the fermentation. I suspect being very accurate doesn’t matter even in business because some brewers have tall fermenters that pressure at the bottom significantly exceeds the pressure at the top…
It's very useful for checking keg pressures. While conditioning or in the kegerator.
If you're wanting to use spunding to achieve a specific level of carbonation in the finished beer, accuracy is important. Or at least knowing the discrepancy in the gauge.
That explains why I have to fiddle with the valves to get 10 PSI when I swap between my plastic fermenters and my mini kegs
