We purchased the Criacr Bluetooth FM Transmitter CP24 so that our expert reviewer could thoroughly test and review it. Read on for our full product review.

The upgraded Criacr Bluetooth FM transmitter is a module that supports streaming music and other audio from your mobile device to your car stereo. It is a compact Bluetooth car transmitter that also offers hands-free calling, support for audio on a TF card or USB flash drive, and two USB charging ports. We have thoroughly tested the design, usability, audio quality and special features (such as playing lossless audio formats) of the Criacr to see if this little transmitter is worth your hard-earned money.

Aesthetically and functionally, the Criar US-CP24 Bluetooth Car FM Transmitter falls a bit short. It’s not the smallest module we’ve seen, but it is very compact at 4.4 x 3 x 2.3 inches and 2.08 ounces. It easily fits into nearly any car’s 12v auxiliary power outlet. The design is fairly simple, but we ran into a few issues during testing.

The Criar US-CP24 feels crowded due to its small form factor and the location of all the buttons, ports, and screen. While the multifunction button protrudes quite a bit, the next/last buttons are located on a beveled edge and are much shallower. They are not as large as the multifunction button and are harder to see and press due to their location.
