This is a decent product. If you are looking for something that will not encumber your line-of-sight to a car's video display then I would recommend this product.
It can be broken down for ease of transport in a suitcase, and the swiveling flex arm twist your smartphone into the perfect viewing angle.
However, I absolute DO NOT recommend this product for anyone looking for a permanent personal-car solution. If use for prolonged periods of time, it will gradually get looser and irritate you for needed to constantly re-tighten the base into the cup holder.
