I have just bought a lighting stand,and on delivery,found there was some damage to a clamp.The company was I say second to none when it comes to customer service.They had a replacement in the post and to me by the next day with good email contact .I now have a lighting stand ready to go. All tel. calls were good and had no problem at all in getting my message across to the company.I have tested the stand and it appears to be fine.I am going to use it with 3 to 4 kg of lighting.
