12.3.2022 Update: Do NOT buy these gauges - they're garbage and leak no matter what you do and if/when you try to contact the manufacturer, you'll get crap service. I don't think it's a coincidence that these gauges have since been drastically reduced in price to $38.99 - as if Sekhmet is admitting that they are junk (they're still not worth purchasing even at $38.99 b/c they leak). You can follow my experience with these newer 25mm gauges here:

Hello AGN:
I've been using the Sekhmet 28mm digital gauges on my rifles for a couple of years now and like them pretty well b/c they were a very nice upgrade from the problematic Edgun EDMU gauges. The Sekhmets not only have better functionality compared to the EDMU, they have a rechargeable battery that provides pretty good life between charges (whereas the EDMU's burned through batteries at an absurd rate and changing them was a serious PITA). The only drawbacks to these 28mm Sekhmets were: 1) they're overkill if you wanted a simple digital gauge for a regulator and 2) they're expensive.
I recently saw that they released a new, smaller and trimmed down 25mm version and picked up a few to use with my FX Impacts. Here is a summary of my first couple of weeks with them:
PROS:
CONS:
[12.3.2022 update: I spoke too soon about the slow leaks in the original post. Shortly after this post, I discovered that the gauges still leaked and I ended up gradually tightening even further with a wrench - and, no matter what, they still always leaked. I wasted a lot of time and air troubleshooting the leaks and ended up sending them back to Sekhmet at their request...and they've yet to process an exchange or refund. I had to dispute the charge with my credit card company - really horrendously poor service from these guys.]
While I was glad to finally resolve the leaking issue, the problem with having to tighten the gauge this much (combined with the inability to flip the display on the screen) is that you'll most likely end up with the gauge installed at some random, awkward angle that might not be easy to read. With the other gauges and the x-ring, you only had to screw it in until it was snug then you could adjust the rotation slightly to an angle that was easy to read. Even if not fully tightened, the x-ring will seal once pressurized. With the 28mm Sekhmets, if that final install position was upside down, you just used the menu to flip the display 180* and problem is resolved - that's not the case with these new 25mm gauges so Sekhmet really should add that functionality to these gauges.
Here are some pics of the gauges and how they're installed on the Impact:
Really, really poor customer service from SEKHMET gauges (I suggest you avoid buying from them)
Hello AGN: [VERY long rant below, the tl,dr: don't buy from Sekhmet Online because they do not stand behind their products and have horrific customer service...] I've never posted this type of feedback for any airgun manufacturer before and I did NOT want to post this at all but the experience...

PROS:
- They're cheaper @ $65/each compared to $96/each for the 28mm gauge
- They're easy to use; unlike its bigger brother, there's only one function (which is to display pressure in bars) so you can quickly and easy see the regulator pressure when needed
- They're smaller and lighter; they work much better on the FX Impact Angle Bracket compared to the 28mm and won't interfere with the cocking motion
- They come in a nice matte black finish so there's no need to use an extra outer cover on them
- The display has bigger numbers, which are easier to read (at the right angle/lighting - more details below in the CONS)
CONS:
- While the numbers on the screen are bigger, the display is reminiscent of your 1984 LCD calculator so the numbers are not brightly lit up like the bigger gauges so they can be difficult to read if viewing from the wrong angle or lighting
- At $65/ea, these are still expensive for what they are - which is a single function gauge
- On the Impact, if you install one of these at the Regulator 1 position, you'll see some weird behavior where the readout will show your Reg 1 pressure, steadily drop about 15 bars then quickly raise back up to the normal Reg 1 pressure. This happens continuously; I can't tell if this is normal behavior for this gauge or if it was because I had a slow leak in the initial installs (more details below)
- There is no menu option (there's no menu, period) to flip the screen so however your gauge screws into your rifle, that's how it's going to sit so you might end up having to read the gauge at an awkward angle or even upside down
