In a former life I worked for a high powered IT company, we sold all IT kit from infrastructure through to tailored software. It was fun and I got paid stupid amounts of money to talk about things I love talking about. Sadly I no longer work there. (I spent rather too much time talking and too little selling.)

However we at the time recommended these products to clients, and obtained several samples for showing off in our showroom. I can at least vouch for the superb build quality. They also sell quite a lot of their devices to medical and high end science markets.

I have just been on the phone to a former colleague who said they no longer recommend them due to availability and now recommends Vogels mounts instead.

EU (UK) supplier of Vogels, though personally I prefer the Egrotron for looks and design.
