This is definitely not for heavy cameras and lenses...
Made the mistake and ordered it only to find out it is elastic. Will not hold a heavy full frame Nikon with 70-200 lens.
This might be ok for light weight cameras, but I would never hang on it professional or expensive equipment.
The quick release clips are something else to worry about. It has no safety mechanism, so any accidental touch will release the clip and open the strap. And it has two of these.
Upon receiving the strap I contacted PowerPlanet for returning it but they wanted me to pay the shipment back too, which made it not feasible to return it. They also have this policy of immediate 7 days return from the day they authorizes you to do it, otherwise they will not refund you. Does not make sense from abroad.
Also be advised that this strap appears about nine times on Amazon as it was few different products.
