I actually prefer human heating pads to one made for reptiles. Products made for humans are held to higher manufacturing standards than ones made for animals and have lower risks of temperature spikes because of that.
Any electrical device can malfunction and cause shocks, temp spikes or even fires so I seek out the ones most carefully inspected and regulated before sale. Then I connect them to thermostats to keep temp spikes under control.
