Today, I've received my THA Nucleus and the Hearth.
Just a little info on those.
The Nucleus is for medium size colony. It is double sized and has removable size glasses. I opted for museum grade glass which blocks UV light and reduces reflection greatly.
The Hearth is a new product. It is much smaller capacity compared with the Nucleus despite of being similar in size. It is only one sided and has only one big chamber. The hearth is to be new home for my Myrmica sp colony.
The Nucleus
This formicarium is absolutely gorgeous. It has a wooden base and two removable glasses. Its outworld is attached by magnets. Everything is held firm and I find almost no flaws with this.
The middle tube leads to water tower on bottom of formicarium. The same tubes exist on the other side.
There is a small issue with this formicarium. It is that the glass has very sharp edges. But this is a minor issue and can be easily corrected by simply applying tape or something. I don't think I'd be opening the glass a lot, so this is almost no issue for me.
The Nucleus is going to be home for Crystal's Myrmica colony with 3 queens and 50+ workers.
The Hearth
The hearth is a new product. This formicarium is going to be the new home for my Myrmica colony.
First of all, it has a surprise feature. On bottom, you can flash light through its water tower, creating a movie effect within the chamber. Because of this feature, this formicarium did not come with a wooden base which has created a small problem.
Because the removable side glass has sharp edges, I fear the edge can be damaged by dragging it around on surface. A solution to this is very simple: just add four rubber feet. 
Tar Heel ant claims it is very hard to add magnets for this nest, so the outworld is held by a tube that connects the entrance of outworld and the nest itself.
