I purchased an Elliptical cross-trainer from Klika which had a faulty front wheel. Their warranty and customer service team did not respond to any emails or telephone calls during the 2.5 months I tried to get a replacement. I took it back for repairs once, but when I brought it home, the wheel was still broken, and the product itself was scratched and damaged. Today, I finally I gave up, returned the product and requested a refund. I will not be using Klika again.
