GN Netcom - Wireless (Cordless) Headset

I've got a GN Netcom 9120 Wireless Headset - It's fantastic, the one main problem is that you have to leave the phone off the hook while you are speaking, and when you finish your talk, you have put physically put the phone down - This isn't a problem if your sitting at your desk, but it's a pain if you walking around the office, etc... Aparantly, you can get a wireless handset remover (i.e. when you open the headset, it pushed the telephone off the base, i.e. opening the line). The headset isn't cheap, but you are paying for a good quality device - I'd definately recomend one.

Why did I write this?
Well, I'm wondering if anyone has tried one of the wireless handset removers, are they good? Let me know.
