I will refer to the program and maps of Navitel.
Regarding the maps, the truth is that until September 2023 the situation was mildly... unacceptable. The navigation program is indeed quite good with sufficient information on the screen (lots of information during navigation) but with bad maps it did not produce good results and you could not easily trust it. However, the maps of Q3 2023 and the latest Q4 2023 turned things around! Good updated maps, good accuracy and good routes (3 suggested for each destination) and relatively fast route calculation, Touch screen with excellent responsiveness and sensitivity. The negatives: relatively low navigation voice volume (you need quiet in the car to hear it), POIs completely outdated (must be older than 20+ years), sometimes disagreement between screen and voice guidance (the voice prompts you to turn, while the screen shows straight, perhaps unsuitable for motorcycles if you rely only on voice guidance because only the screen shows the correct route). In terms of settings, it does not have great flexibility and options, only the basics are available.
It is a good alternative GPS device. Of course, it cannot be compared to Google Maps on mobile.

By far the worst GPS Navigator I have ever experienced in my 62 years. Its menu is completely useless and its usage is very complicated. It does not allow you to make many settings so that it constantly takes you to secondary roads with difficult access, even for goats. I would only recommend it to my worst enemies who I want permanently disappeared. Truly, I bitterly regret the wasted money I spent on buying it!!!

At the price it is, I consider it a very good choice. I used to be a Garmin customer, but because I didn't want to go for a more expensive product again, this time I preferred Navitel, following the recommendation of an employee at an electronics store who was very satisfied.
Among its positives, I could mention the speed at which it calculates or recalculates routes, its fast and beautiful interface, as well as the fact that it doesn't require any kind of internet connection. Finally, the windshield suction cup is made of very good material and perfectly holds the weight of the GPS.
The main negative is that when it came into my hands, it had the 2018 maps, resulting in several parts of the routes I had chosen changing by July 2019. It was therefore necessary to update it through a computer. Unfortunately, the company's servers do not send the maps at a high speed, resulting in the upgrade being very slow and requiring endless hours to complete. Another negative is that during the map upgrade, a specific country for updating cannot be selected, meaning in our case Greece, but the entire set of European maps must be upgraded, resulting in a time-consuming and unnecessary process. It goes without saying that if the process is not completed or the computer is turned off before the download is finished, then the upgrade must start again from the beginning. But now that I managed to do the upgrade, the maps are amazing and the experience with the device is incredible!
