Do not leave negative feedback unless the other person has already left you feedback to avoid a tit-for-tat senario.

I left negative feedback for a seller who;

Didn't respond to 5 daily messages requesting reply.

Waited 7 days before writing honest feedback.

Two items didn't fit. Wrong model sent.

Description was for 5-7 days delivery, but took 17.

I paid immediately through Paypal. Only inquired for location of items after a 7 day wait.

Left one negative and a nutral. I received 2 negatives for being honest.

Never purchase from, 'screen-guard' who are based in Germany.
