Quick delivery, items are as expected and good quality.
Got this as a gift for my husband and he loves it! Great quality and fits a ton of cards.
My betta loves to make his bubble nests in here. And while he is not a long finned fish and doesn’t use it for resting, he does love to hang out in it. Only additional thing I did was get different grit sandpaper to smooth out the inside so nothing like loose filament would catch on fins.
Well I brought it for frogs, snails and fish. Didn’t know if they’d take a liking to it as that isn’t the intended audience but… wish I could add multiple pictures. Everybody adores it! I tend to keep it fastened down to one particular spot, as they’re less responsive when it’s floating around everywhere. Glad they enjoy it!
Absolutely perfect, what I expected! Pepper enjoyed wearing it, he didn’t even try to take it off!
Product was a good gift and is sturdy, however it is noticeably 3D printed, but not that big a deal
This item is excellent and exactly as described. Perfect for my bettas. They love them.
Works great and is easy to clean. I like that it's a single piece. It floats well and doesn't kick up the sand. I'd previously purchased a stick on diffuser with a swappable base, and it's not nearly as user friendly.
