I have been very happy for my old dog a Leuchtiehalsband since now 7 years of use, and agree to. Only the change of the batteries is time consuming and tedious. For this reason, I put me on my second dog to the Premium Leuchtie. Unfortunately, the inserting or changing the batteries is not much easier than the previous.
Conclusion: The premium Leuchtie is more expensive but offers no improvements. I can therefore only advise everyone to buy the cheaper standard version.
