Brand new Zgemma H7S probable hardware fault

[world-of-satellite.co.uk]

Can anyone who bought a H7S from WOS recently tell me, is it normal for the plastic film over the front to have big bubbles under it when it arrives?

Yes they can have.

I still suspect I was accidentally sent a customer return instead of a new unit.

Impossible, this cannot happen with the systems we have in place.

Not that I care, I'm just worried that because the fault comes and goes they'll fail to find a fault and charge me for removing the film.
The fault does seem to be getting worse though, which helps.

What fault exactly do you have? You reported Tuner A not working, but in your support ticket you clearly stated it did scan. Issue could be caused by the distribution system you're connected too. We'd need to inspect and test the unit.

There doesn't seem to be any obvious sign that they track serial numbers.

I suggest that you check your order update emails, I'm 100% sure you'll find serial numbers from your receiver and the hard drive we installed for you.

RMA instructions have been sent to you, return the unit. I will personally inspect and test the unit. If faulty we will replace, simple. No need for posts like this.
