that industrial strength velcro is definitely strong. it takes a bit of effort for me to remove the accu-rite (i tested it to see if it would hold up to my snake slithering over it like she does).
this is how/where my accurite is mounted. its on the back glass in the middle between the 2 water dishes...



a close up (its at the top right corner of this pic)...



the hide boxes have been upgraded to bigger ones since those itty bitty ones ended up being turtle shells on my snake haha.
