Will the small balls at the ends slip?

Having never have slip while using them as long as you remembered to tighten the clamp. The friction from the silicone ring and the clamps, which can be adjusted to obtain by adjusting the clamp locking.

An extension arm has two length sizes, how should I choose?

From this end of the ball to the other end of the ball is the overall length of the extension arm, but according to the actual size of the product that can be used, it should start from the red silicone O-ring.

Perfect

Excellent quality and exactly what I needed to draw my light a little closer in. The items arrived in a neatly packages box and were in perfect condition. The quality seems very good, although I have not had then in the water yet. I would definitely buy this product again!

Brazo de extensión de aluminio

Los brazos de extensión de aluminio se ven fuertes, los he probado con las abrazaderas y funcionan bien. El O-ring rojo del brazo de extensión no parece que va aguantar mucho tiempo, no es de un buen material.

Nice budget arms

I've been diving with these on my compact camera rig for several months and they seem to work just as well as the pricy Ultralight arms I have on my mirrorless rig.
