I made a mistake when ordering. A quick e-mail and the error was rectified immediately without any ifs or buts.
Many thanks for that!
Otherwise, fast delivery and very little packaging waste. Keep up the good work!

Is very much fun

I bought the e-fin. At the 2nd attempt, I got it then how to hold the transmitter that he is facing you, and then it ran great. Makes total fun. The transmitter is then unfortunately broken, and Jaykay has exchanged the part without complaint, just had to call and the package was already in the mail. Highly recommended. Everything fine.

The product and the service were exceptionally good. Questions were sometimes answered just minutes later and a solution was always found quickly. That's what you hope for with other providers. Very gladly again.
