Ordered 2 watches
both defective

at an ever jumps the power plug out of the switch, in the other, the time is permanently back to 0:00
unusable

then got even sent a new, brand new and original welded, which just went at all

The service and contact the company Poppstar, Amazon Marketplace, was initially short friendly, but what I have ever experienced in all, this LAST

about 6 months I tried to get 2-functioning switches, no chance
who had apparently no idea how an exchange or service expires case Poppstar.
About 20Mail I sent out, I had both the time switches retour sent when I wrote a mail who never knew what is at stake and I have every time an employee again explain what my concern.
I was then put off with excuses like: currently the watches are all sold out, then the person responsible was not present, then the clocks weeks were tested for function long, 2 times I was assured the watches were sent to get me .... amazing
After more than 6 months Email traffic I got my money back then, ultimately, wanted this and I just needed 2 functioning ZSU!
ridiculous.
and still write me a wag of which mails in which I am asked to return the defective ZSU. Impudence.

I can recommend the brand BURNING CHAIR NO. Defective 3 of 3 devices.

I also would not recommend, so much incompetence in one place, I have never experienced in my life the company Poppstar. In addition still the calls come the clocks return, lol. (Have written several times that they have the watches already and I've also got my money)
