I’ve tried a couple experiments with tiny aquariums in jars and bowls (0.5-1gal). The water parameters can be tricky to stabilize since the ecosystem is so small and any changes (like feeding food) can cause major swings. I would definitely advise plant heavy, and stick to small invertebrates like snails and shrimps and avoid fish.
I’ve purchased a pair of Emporio Armani glasses through them, and a pack of their Kits brand daily contact lenses.
The lenses are nothing special, but they were a decent price and worked just fine. I tend to have a difficult time removing them, but that just might be me.
The glasses are designer brand so that doesn’t speak to their in house brand quality. But they had a good coupon going when I bought them so it ended up being a good price as well.
Overall I would recommend the Kits for the prices, but it probably won’t be the highest quality stuff if you’re going for their own brand.
