Hello

Can someone point me to information about returning electronic goods which were purchased online (from a Swiss store)?

The company's terms & conditions say no return if the product was opened or used. However, the item doesn't work. Is there any Swiss law about this?

If not, then are there insurances for this type of situation?

Many thanks

Please give more details of the item and the defect. I had to return a new hardware drive to Digitec that didn't work. They were happy to exchange for another.

If it's a genuine defect, they should definitely exchange it. But naturally, they're wary of people who've bought something then simply decide they don't like it, and want their money back. Not the case with you, I'm sure, but there's no obvious reason for them not to replace a genuinely faulty device.

You don't want to return, you want to claim warranty. Their T&C should mention how to do that.

It's a Huawei fitness tracker from Techmania: https://www.techmania.ch/de/Product/Detail/26869479

The issue is that the Huawei health app doesn't install properly and the product can't be used on its own. I did a lot of research in technical forums, seems this is a common issue - I think it's related to the Huawei/Google issues, at an operating system level. Neither Google nor Huawei admit the issue. I also tried installing Huawei operating apps but I think Google blocks this.

Amongst the functions on Techmani's website it lists:
Benachrichtigung bei Nachrichten (iOS/​Android)
Benachrichtigung bei Anrufen (iOS/​Android)
And obviously my band does not have these features, as it simply doesn't work with Android. So, does not function as described.

In UK law this could be breach of contract or there are rights under various consumer laws (item must be as described, fit for purpose, no unfair terms and conditions allowed, etc).

Obviously this doesn't exist under Swiss law, just depends on the company's terms and conditions:

Re warranty, they say I must take this up with the manufacturer myself (despite the fact that I have no legal contract with them), nothing for Techmania.

Honestly this is not a big expensive item and didn't expect to get any money back. I was mainly interested about the principles, because I will surely buy more things in the future, they could be really expensive, and I would like to have some protection if they break after a few months. It seems like it is quite risky to buy things in Switzerland.

I've had problems like this before.
The stores have claimed no responsibility, sending it back to the manufacturer is what they do too and of course, in cases like yours, a hardware test will find no fault so it will be returned to you.

You'll end up with lots of unusable hardware if you are not careful.

Let us know how you get on. I refuse to buy anything at Techmania due to problems in the past.

Just sayin' but Digitec have a fairly reasonable returns policy. I don't buy from online retailers that don't.
