i have to say for the price they are good value. now the only flaw i can see is the ratchet band to tighten the bars.. they are flimsy and also to release the ratchet bar is tough. but overall good.
i would also like to thank customer support on this one. my order was delayed for some time,i contacted them and immediately they responded and sent a replacement..the original ones arrived.i contacted vevor and they said i could keep them brilliant.
