The MOTOTRBO range of products by Motorola is the defining brand within the DMR standards. This is the case with regrads to performance as well as quality in design and production. Being trendsetting as they are, MOTOTRBO products are often copied maliciously. This way rogue producers victimize the end users. To avoid purchasing copy products of questionable quality, and to make sure one gets the best possible service, all purchases should be made through reseller partners, which hold the proper authoriszations.
