I purchased this electronic photography accessory from Shield Distribution thru Amazon.com. The order was placed on March 20, 2015 and the package was received in Miami, Florida three days later. It just can't get any better than that. No delivery charges were made. Delivery service---first class.
The radio devices worked perfectly on my DSLR Canon EOS Rebel T2i camera and on my Fujifilm X-30 mirrorless camera. The Yongnuo RF-603C II radio units performed flawlessly, as advertised.
On several occasions I used the radios as a remote control unit. One was attached to the DSLR camera and the other one was operated by me as a remote control. The camera was nested on a tripod and I was shooting in very slow speed, thus the need of a remote control to avoid camera shaking. The radio were great.
Overall, the unites look and feel cheap, specially the locking rings. On several occasions they get stuck up and it becomes a very cumbersome job to get the wheels moving again. The cheap plastic makes the threads weak and vulnerable. Since the units are so light and fit so tightly on the hotshoes, I have decided not to lock them. Too much of a hassle making these wheels work when they get stuck. I didn't like the design of the wheels. Difficult to turn them with ther jagged design.
Another problem, and this is a big one, is the tight fit of the radios on both the camera's hot shoes and a Yongnuo Speedlite YN565-EX. It's a real problem getting them to slide into place on the hotshoe. Sliding them out is a breeze, though. For example, the problem is so great that I gave up installing them on my Fujifilm X-30, because I fear I could damage the hotshoe. The same problem persists with my Canon DSLR camera. The low manufacturing quality of the units make them almost impossible to use. If I had known of this problem, probably I would have purchased a better quality product. I hope Yongnuo will listen to these reviews and upgrade their products, since they perform great except for these manufacturing and design flaws.
But I guess you get what you pay for. The price is very affordable, and that is why I decided to make the purchasing decision. If the hotshoe problems continue, I'm seriously considering upgrading to the Yongnuo YN622C TX E-TTL wireless flash transceivers. I understand they are the best and most affordable wireless flash triggers than uses ETTL for Yongnuo YN565. I hope that the locking mechanism is better than the RF-603CII and the design of the hotshoe mechanism is better. If anybody knows about issues with this product, please advise through this channel, to avoid making another mistake.
Other than problems described, these radios are a great product for off-camera speedlite photography. However, Yongnuo needs to polish them some more. I honestly think three stars is the best rating I can give this product.

Tried a Viltrox J-120-C1. With new batteries could not get the trigger to work reliably nor
to work unobstructed beyond 9 feet. So was returned.
Ordered Yongnuo RF-603C1 II after seeing video on Youtube about operation and flexibility.
The trigger is set up on a Canon T3i . Packaging and documentation good.
The subject was very wary bird life.
Took more than 500 remote images in past week with RF-603 II.
Sometimes in the sun all day on a 95 degree day.
Trigger button action worked each time, every time.
Half press to auto-focus, full press to trigger the shot. Good, battery life.
Verified operation at 30 meters where the signal had to go through window blinds,
double pane glass, window screen and camera covering.
So my expectation is the RF-603 may work as claimed at an unobstructed 100M.
The status lights on each unit show connection and triggering are not too bright for night work nor too dim in daylight.
The result is the desired image was captured.
