GPS Accessory for Clicgear or other pushcart

I've got a Clicgear 3.0 and I'm looking at adding a GPS holder to it.  Right now I'm looking at the following - http://www.amazon.com/View-Golf-Cart-GPS-Holder/dp/B001BRWL5S/ref=wl_it_dp_o_npd?ie=UTF8&coliid;=I3FO80EPUXOWLA&colid;=2LLAJ79LTIOY2

I have a SkyCaddie SG4, which is pictured, so I'm assuming it fits well, and this specific holder appears to allow for other attachments to still work (like the umbrella holder).

So do any of you use this one or others?  Do they work well, meaning is there any concern that the GPS unit may fall out?

I've had that mount on my Sun Mtn Speed Cart for over a year now. No problems, works great and the umbrella holder still works. GPS is very secure because the nub on the back actually snaps in so you have to manually release a lever. It is also surprisingly durable too. Last season I let my cart go down a long hill by itself, hit some kind of debris and bottomed out on the GPS/handle area without damage and GPS stayed secured.

I too have that holder, but I was as fond of it as I am of this one, http://www.tgw.com/customer/category/product.jsp/SUBCATEGORY_ID/22022/refScid/1255

The one you are looking at has the GPS hanging down below the handle, the one I prefer the GPS sits above the handle.  It still allows for the umbrella holder.  Not much difference between the two, I just found it easier to read when the GPS was higher and closer to eye level then down low.  Which ever one you chose they work great, I swear by them, they really make selecting a club quick.  You can see the distance as you walk and you have an idea of the distance, it only take a second or two when you stop for the GPS to catch up and you can pull a club and go.  Much better than fumbling around with the GPS when it is hooked to your bag.
