Summary: I love Garmin products. This is the third in series of handheld Garmins I have purchased. It works quite well. I use it for geocaching, hiking, and kayaking. I know where I am and where I've been.
Summary: The GPS was great! The TOPO map loaded very easily after putting in in, but had a few minor discrepancies on some of the finer details of the location I was using it for. Road, river, and camp locations were slightly off from real sites, but I was able to use local signs to get where I needed.
Good product. I question the value of the TOPO 100 map.

Summary: The eTrex30 works well and is easy to use. Battery life seems very good. Easy to get the device to communicate with BaseCamp software [though I had to contact Garmin by email to get the map initialization to work].
