Although the radio trigger makes no particular impression, but serves its purpose, in my case at a Pentax K-30, good. Easy trips and long exposures in the B mode are not a problem.
The processing leaves something to be desired. It is also annoying that the remote control has no on / off switch. Tucked you this, it may be that something is on the trigger button and thus sends continuous signals. This is of course at the expense of battery.
