Internal battery I guess is ok, but I much prefer mods that can hold a single 18650. I was going to say go for the S macro from there, but they only have the mauve color left. In the last 2 months I picked up 4 of those s macros and they are awesome. Of course they are only 40 watts, but they are authentic dna 40's . That along with the replaceable battery, small size, and like 28 bucks, it was hard not to get. I love the looks and size of that mod however, but I always have just felt that once that internal battery goes, so does the mod. Good luck
