Really impressed with the customer service attention.
I got the replacement of a battery cap in just two days.
That´s exactly what you expect from a good brand.
Thank you very much.

O-ring broken

I have my power meter for about 2 years and had to change the battery a couple of times. The O-ring is broken and the meter now has connection and meassuring faillures. Could you help?

Battery cover sealant

Battery cover sealant is poor quality. Humidity goes inside.


Estoy muy contento con el potenciometro y su funcionamiento, pero he perdido la tapa y veo que hay problemas para conseguir este respuesto. ¿vais a tener repuesto de la tapa?. Siendo algo que se puede perder con facilidad el no tener respuesto de la tapa para mi seria para darle muy mala valoración, no puede ser que te gastes tanto dinero en algo y que despues por una tapa que cuesta 15 euros tengas que tirarlo a la basura y comprar el potenciometro de nuevo. Espero que su servicio de atención al cliente se ponga en contacto conmigo y podamos encontrar una solución.
Muchas gracias.
I am very happy with the potentiometer and its operation, but I have lost the cap and I see that there are problems to get it. Are you going to have a replacement for the cap? Being something that can be easily lost, not having a replacement for the cap would be to give it a very bad evaluation, it cannot be that you spend so much money on something and then for a cap that costs 15 euros you have to throw it away and buy the potentiometer again. I hope your customer support will contact me and we can find a solution.
Thank you so much.
