Just another product that may be useful in very specific circumstances but is made available to the poorly-informed buying public who are only guessing what their animal's problem might be and who won't spend the money on the appropriate vet...but expect a non-specific off the shelf product to work a miracle anyway. OP if you own a severely dehydrated reptile that would normally soak itself periodically, maybe this product would be useful. If you don't own a reptile like this don't bother. A chameleon would not normally soak itself and may panic if forced to. As for geckos...too diverse a group to even guess which ones would even tolerate the electrolyte solution. Save your money. Hydrate your chams and geckos in a more natural manner.
