I purchased one recently, easy to use.
The speed is displayed for a short period of time on mine.
Mine reads 20+ fps low compared to my Caldwell.

How do you really know if the Caldwell is not reading high? ..... You dont in the end. Theres no calibration way on any . You use it at face value out of the box and hope it close to correct..🤔

Go figure. If the manufacturers just tricked the units to read always 100 fps more, they would make us all happy!!! LOL.

Once you use it You’ll get ideas on how to focus its convenience to your shooting.
I haven't tried this yet but I plan to build a saftey cage for it, and put it out at range to read long range balistics as a test. Referring to the Fx pocket radar.

Well you kinda know if ones bad off .

You shoot this gun using this one pellet that tested combo shows 880fps . So if your ballpark in a few +/- well ok. If way off not ok. Thing and trick is a way to know. One i use as a baseline is this chart.

I shoot the crosman and at the muzzle is 647. Im getting 655 or say 648. So i can kinda say im in the ballpark and this crony is pretty close..

BUT!!! .....lol. you still got to know that the gun is in top working condition to.. then anything subject to gail at any given time.. a crony out of the box not knowing is faith based.

I have borrowed a Caldwell that's the newest one that has Phone app connectivity. Thing worked flawlessly on a Diana 48, Diana pistol, and a Stoger X20. Carrying case was very nice tho the bag was very tight and you had to get the parts in just right (same as how the factory packs it)

There is a free phone app called Chrono Connect which uses sound (and a phone), but I never got around to seriously using it.
I have a Caldwell + two 24v LED strip lights stuck to the lower surface of the two white plastic diffusers + a 24v power supply/adapter to power them. That makes it work indoors, IF you turn off all fluorescent lights that are near it.

I first bought one like Geezerhood already illustrated and have been using it recently because I nicked my other one with a pellet (knockouts exit the muzzle wildly in my P35-177) and it stopped working. The clamp on works fine I just don't like clamping it to the muzzle. I can shoot groups while using it but it shifts POI a little so I still have to sight in when I'm done. I prefer one that can be tripod mounted and has a little bit larger shot window and costs about the same. I have not seen them on Amazon but if you search aliexpress or use a link to the clamp on one it will be in the "similar items" list. I paid $30 including tax and shipping for the one I just ordered. It has a decimal place on the velocity if the replacement is like my older one and my clamp on doesn't. Not sure it matters, they may not be that accurate, but mps is a little crude for velocity and the decimal place fixes that. I think my old one read a mps or two higher than my clamp on but who knows which is more accurate.

I used to have a shooting chrony traditional but I shot it one too many times trying to get a reading indoors without added light. The little cheap ones are more reliable and don't even need batteries. They are rechargeable. I wouldn't mind knowing exactly how accurate they are but I don't think there is an easy way to know. I am confident they are plenty accurate for what I am doing with them (tuning my PCPs). They are very consistent and if they are a few fps off it doesn't really matter. Highly recommend. I agree with the comment that the small shooting window makes them not very usable downrange (although if you hit one they are cheap enough it isn't a tragedy) but aliexpress also has some that look more traditional for similar prices. No idea how well they work.
