Not familiar with that particular model. I've got a GunVault biometric gun safe. I can tell you it will take being dropped by a small child rather well. I also like that I don't have to remember a combination or fumble for keys at 3am if something goes bump in the night. Definitely don't think it is "robber proof" as you could get into it with a pry bar. But it will keep my 6yr old out with ease.
looks similar to the model you mention and you can buy it much cheaper on Amazon:
I don't know what your space requirements are. But I have the MicroVault
Again, much cheaper on Amazon:
If it's a little easier on your pocket book.
