It's not that hard to connect up, but you could buy the tape & connectors & a thermostat (sold separately) & have a handyman
hook it up for you. I've always done my own, but it's been a long time now...mine hasn't worn out. What I also like is that it's
low-wattage. I only have 16 snakes right now, but you don't want to know how many snakes I used to have, lol...and a house
full of Flexwatt barely dented my electric bill. But again, what kind of snakes do you want to use it for? Might not be the best
option for a BP...they need warmer temps. Also you can't use it IN a cage, it must be underneath ("UTH") so you also wouldn't
use it under a wood cage, for example....the wood is an insulator & would not allow the heat to rise into the cage enough. It
works great under glass tanks, which is my preference for what I keep. It also works under plastic/PVC cages (which I don't like
or use).
