Don't waste your money

I work in law enforcement and deal with the results of Preliminary Breath Tests (PBTs) constantly. After drinking about 6+ beers with some friends one night, one police officer friend brought out a professional, road tested breathalyzer for use on actual DUI investigations. I blew a .05 on this device, after waiting the prescribed 15-20 minutes after my most recent drink. I blew a .14 on the professional breathalyzer. Usually the professional breathalyzers are off by a factor of 10-20% from the actual BAC result via blood draw. Hence, their inadmissibility in court. However, this device gave such a drastically incorrect reading, and did so consistently, that it could not be trusted. My friends also experienced similar poor results with this. I had just purchased the device and put a new battery in it, so I know it was not that. I would spend the extra $50 bucks and buy the $80-$85 version of their product if you want a reliable breathalyzer.
Also, anytime a breathalyzer registers positive for the presence of alcohol, one should not be driving a vehicle. Impairment truly does begin at the first drink, and sadly, examples abound about individuals receiving injuries or killing people after having BAC results that are actually *under* the legal limit. Even if you are in an accident and not at fault, you can get a DUI.
In any event: this is a chintzy product. Skip it and pay a few dollars and get something more legitimate.

Very well-thought out wireless product

This may shock you, but this product actually works precisely like it is described in the specifications. One thing I noticed in reading the reviews is that the Rocketfish wireless transmitter sends its signal on the 2.4 GHz frequency, which is the same frequency used by wireless 802.11(n) transmissions. Thus, in some situations, given specific environmental conditions in your operating environment, there may be wireless interference while using this product. That being said, I have not experienced such issues so far and I have two wireless devices sitting right next to the wireless transmitted for these speakers.
I bought this to send a signal from my A/V receiver to a whole different room, as a kind of work-around for second zone sound on an A/V receiver. At $80 on Black Friday for a new product (and $80 otherwise, open box) that can't be beat. Basically, I am a huge sports fan and wanted to listen to the game while I was in the shower. When I tested these out, they worked so well I had to actually use them for their intended purpose: the back two channels in a surround sound set up.
Please note, if your room is set up such that you must use wireless for the side two channels as opposed to the rear two channels, this product can handle that, too. Just use your imagination. You can literally send an audio signal anywhere. This is kind of a cheap work-around for a Sonos system as it allows a set of speakers to be placed wireless in another location, not in a line of sight with the audio source, and to be controlled by the same method which controls the audio source.
The sending unit and receiving unit are paired at the factory (per the instruction manual) so you do not have to mess around with pressing buttons or getting onto your router and setting IP addresses, etc.
Overall, I'd recommend the product. You can have this up and running in five minutes, tops.
Please note: both the sending unit and receiving unit require a power input, so mentally note the placement of your electrical outlets and be sure to plan accordingly. The unit comes with only one set of approximately 18" speaker wire, so you must have speaker wire to connect the opposite sender/receiver unit.

What's great about it: Works as intended, easy set up
What's not so great: Has a glowing blue light on the unit that will always glow as long as it is plugged in
I would recommend this to a friend!
