It is easy to use for both techs as well customers/clients! The customer support from ETASystem can be very slow at times but it's still better than most other companies out there in this industry!! I have had no issues with my tracking system so far (aside form some occasional lag time when using their site). This product has been used by our organization since day one which makes me feel like we've made an excellent choice here - not many products last that long around us anymore nowadays though ;) We are able track vehicles across multiple states without issue or problems being encountered currently due mainly because they were built correctly right off-the bat back then :) If you're looking into purchasing something new make sure your sales rep knows what was done before hand otherwise things could get expensive down later if changes need making after purchase date.
