Not comparable to a Fluke but good and great value for money.

Frequency measurement specified up to 10 MHz, I have successfully measured up to 25 MHz.

Just to add that the transmitters are OK and worth alone by the price, but the receivers are absolute crap and range will be no better than a few meters with that receiver. A much more higher cost receiver will bring range up to 100m instead of 2/5 meters. 
Bargain is about price/quality, not only price so there is no need only to list the cheapest ones. Got a link with better ones that may be more expensive but still attractive?
btw, I was able to reach 25 meter while going to glass with these. That’s not that bad and suitable for many simple remote applications but i can imagine better ones are available.
Yeah, sure: I’ve tested the RXB8 receiver, and my range went up from 2/5 meters to almost 100 meters, part in building, another part in free air. With this receiver I’m able to monitor stuff that is away and has to go through some thick concrete walls and levels:
One example with -144dbm sensitivity:
Other example, that is more expensive and I didn’t tried:
