Indoor rock climbing holds. Which and where to buy?

[JeffersLos]

Our 2 teenage sons have enjoyed doing indoor rock climbing the last few months at a local indoor rock/wall climbing center.

 

There's a long indoor wall near the back of our house that could be used as an indoor climbing wall.

 

The holds or grips at the center they go to aren't the best quality, so I don't want to ask them where they source them from.

 

There are ones on Lazada that are really cheap, a few hundred baht for 5 or 10. I imagine that they are light, bend, crack and break rather quickly. 

 

Does anyone have experience buying decent, strong indoor climbing wall holds with concrete anchors here?

 

TIA.
