Since the order to the Krasnoyarsk territory 29 days. Hung cargo 6 kg, normally withstand. The only thing, you need to lower the head restraints to the end, so that the hooks were pressed, otherwise their opposite side bulges up.
I bought 10 pairs in total, a product made of plastic weighed 35 grams, one came to about 3 pounds. I recommend the product and seller. Front seat headrests are no thicker than my Sparrow bar. I'll use lada samara and elentrada.
