hello mannet22, welcome to the Nexus
I checked both those links and I wouldn't go with either.
The first look very similar to a device I have seen before, it claimed to have a ceramic sponge which controlled the temperature flow but when tested the ceramic sponge just melted giving off dodgy fumes. The second is just a fancy looking crack pipe which will provide conduction heating which isn't ideal.
My advice is always to infuse your DMT into some herb using IPA/acetone and then just smoke it in a smallish (30cm) glass bong.
hope this helps

it's all in your mind, but what's your mind???
