Hi I live in the UK and a couple of months ago my friend bought a Tunze Wavebox from a company in the Netherlands, after only having this for about 3 weeks it stopped working and the driver box got hot so you could not touch it. I got in touch with the company that he bought it from and they told him to return it to Tunze Germany, which he did at a cost of £21 UK pounds which in fairness the company in the Netherlands refunded. Now after only running for about 3 weeks after being repaired it has stopped again and the driver box is getting hot again. I contacted the company of behalf of my friend and asked for a full refund on this item as it had failed again and he had lost all faith in it. I was told to get in touch with Tunze Germany and that it was up to them as what to do about it. My question being has anyone on this site had any trouble with the new improved Tunze Wavebox and if so what, i believe there is a Tunze man on here who may be able to tell me and give my friend some answers as he has a product that he paid £300 for which is not working after being repaired only a few weeks ago. He does not want this item repairing again he just wants his money refunded so he can get an alternative. Thanks Eric
