Not to judge rationally

Rational considered this device is cheaper and vastly overpriced junk from China. Cheap plastic that the flashing a limited range of sounds from up there (8) and a couple of lamps tired to do so. All in all, probably not even worth 1. But, that's just Star Trek and even if the device has only limited resemblance to the Tricorder from the series, it's a great accessory for any occasion when you can wear the uniform.

Packed the device in a bulky display packaging, a lot of plastic waste was so. Next waste came with the accompanying batteries into the house that had been empty and had to be replaced by new ones thus equal. There is a clear point deduction. The second point loss is due to the price. The third point is forfeited if the miserable quality.

But that's Star Trek and solely, and for that the like is still available, there is a bonus point. Trekkies can probably be happy with the tricorder, all other certainly not.
