I've just ordered this, so my review is a first impression, I can't yet speak about its long term use.
Regardless, It has impressed me!

Visuals: The product looks very good, much more appealing than a simple glass or plastic container. The lid and connecting formicaruim are very interesting to look at and have a lot of character over the usual square ones found online. The red glass covers are a nice addition to the formicaruim, allowing for easy viewing of the ants while not disturbing them too much.

Dimensions: these are as described but the measurements of the outworld seem to be excluding the lid and connecting ports. So it's a few cm bigger than advertised, but no complaints there!
(I've put a British £2 coin in the photo for scale)

Quality: the build appears strong and durable, the connections / lid fit very snuggly, a perfect match and it feels like good quality when handling it.

Longevity: as previously stated, this is just a first impression but I really like their additional port on the other side of the outworld which would make adding more formicaruims and outworlds easy. They also have different adaptors, one that is direct to their existing products and also a pipe connector so you can add their products to something else if needed.

Postage and communication from the seller: Excellent on both accounts. I was aware of when my package had set off and was sent tracking info. It arrived slightly earlier than expected too. The product arrived well wrapped and in excellent condition.

Cons: the opening into the outworld is a little small, so I had to use tweezers to decorate and I will have to do the same with feeding the ants. Not to worry though as the additional feeding tray supplied comes with a convenient long handle for easier access. I'm not 100% sure how easy it would be if I had to clean inside the outworld, again I presume tweezers would be needed.
I'm a little worried about disturbing the ants by opening the ports on the formicaruim to add water. Though these are easy enough to open and a very nice touch. If I were being really picky I would have had a small hole in the top of them to put water in via a syringe. It would have been a nice touch, but regardless, I love the easy access idea and ability to replace the sponge if needed.

Overall: a brilliant product, I would highly recommend it. I'm very happy with all the major aspects of this and I will be happy to purchase from ant keepers again in the future.

Please note: The decorations inside the outworld in the photo are my own and the photo was taken just prior to adding the ants.

The Antgate is a great idea, it allows me to connect different things to my formicaruim, currently I have connected my test tube directly to the formicaruim for the ants to have an easy way of moving without stressing them.

This works great for connecting the formic with the outworld. I've also used it to connect my starter test tube to the Formica to move my starting colony.

I've got 3 Messors queens and these test tubes are large, providing lots of room for my young colonies to grow. The stand that comes with them is great for stopping them from rolling around and stressing the queens. The material is good quality. I also bought the ant keepers book and it was very comprehensive, telling me everything I need to know to get started. Thank you AntKeepers!

Blev riktigt nöjd med köpet

I bought a few starter pieces from AntKeepers. Test tubes, a small Formica and some connections. I think the quality is very good. I love the 'ant gate' idea and the hydration ports on the side of the nest. The connections are great too, I can link Formica together or add in a test tube/ piping. I will be ordering again from here in the future!

Både 3 och 5 ml är välgjorda. Precision på hög nivå.

Formicarierna är verkligen något extra! De är inte bara tillverkade av kvalitetsmaterial, utan också genomtänkta och otroligt snyggt designade. Så snygga att man vill ha dem framme och visa upp dem för alla! Jag älskar när en tillverkare lägger lika stor vikt vid design som vid funktionalitet, och här har de verkligen lyckats. Inspirationen från naturen är tydlig, och det ger hela formicariet en harmonisk känsla. Och färgerna – wow! De är både stilrena och livfulla på samma gång. En riktig fröjd för både öga och sinne!

Amazing kit

Fungerar bra för ändamålet

Amazing how it all looks and how natural it is for the ants. The only issue I had was the outworld lid was twisted and does not fit how

Rekommenderas! Lätt att fylla på och håller ett tag, mina hästmyror gillar den med Sunburst ant nectar i.

Liten och smidig att använda.

Vi är supernöjda!

Smidiga och bra.
