Innokin itaste 134 - Humming sound

[BeRight]

I have several innokin products: MVP 2, VV/V3, EP, SVD and 134. All of which have been performing well.

I have been using the 134 daily soon after it first came out.

Today when pressing the fire button it has a humming sound - reminds me of a humming transformer.

It does this on a fresh or battery in use.

Have any other users heard this noise?

Any tips?

Is it near end of life?

Thank you in advance for your responses.
