[TowerTalk] Greenstone vacuum relays

[Tõnno Vähk]

Does anyone have experience with products by Greenstone, especially the
vacuum relays:

http://www.greenstoneusa.com/vacuumrelays.htm

They are supposedly made in China and cost several time less than say
Jennings, etc..

They are sold by for example RF Parts:

http://www.rfparts.com/relays/relays-vacuum.html?p=2

and MAX-GAIN:

http://www.mgs4u.com/RF-Microwave/vacuum-relays-SPDT.htm

VC-2 sells for less than USD 100 while equivalent Jennings is over USD 300.

Worth taking a risk?

And then there is this special offer for hams by Gigavac:

Anyone tried those relays?
