Have some issues with water getting in but it may be that hair is caught between the mask and my face.

I tend to drop a bit of water when I close it, probably simply because I haven't got my hand to mouth coordination together yet. Lol. Really like the color and size

I like it but st times it can be hard to duck the water out.  Also, the locking mechanism can close the valve if twisting it while trying to drink.  That can be frustrating when your thirsty with no hands.

they seem to be working but I am not sure as over time the water tends to have a taste.

This house is really cool and big ! Only problems is that since the door opening is so big it gets wet inside which means it's not actually waterproof!!! If it had something to cover that opening maybe some plastic curtains would be good. For the price if you live in a place that doesn't rain to often then it's really good. Not the best quality but decent

It is also hard to fill it with water, without spilling.

I will try to change location, see if it helps.

So far, no luck!

Way better than the problems I was having, but I have to say that the water pressure is very weak. Looks nice. Easy to install.

still have some slight issues with blinds opening and closing, but its probably from a deeper issue than this part. It works well

So here's the deal.  This thing WILL get water in it the way it comes out of the box.  For some reason that I don't understand, the makers of this product have put three small holes on the underside of the toy that lets water into the interior compartment.  I'm not sure why they did that because even though the interior with the electronics is supposed to be protected from the water by a gasket - the gasket doesn't really work at all and water will get into the battery and electronics compartment very quickly.

The simple way to fix this problem is with three small pieces of gorilla tape or some other waterproof tape to tape up those three holes.  Doing that makes the toy 100% watertight and it works perfectly!  My baby loves it and it has not gotten any water inside since we taped those three holes.

I bought this to use at work and am generally happy with it. There is one odd thing though. If I fill it by removing the reservoir, filling it and then re-installing it, it will not pump water properly. I called for support and was given some things to try that didn't really work well. Oddly enough, if I just fill the reservoir by pouring water into it from a bottle, it works just fine.

it's great but some parts(the attached photo) need to be tight very well and some times there is some leakage.

I assume it works well. Hard to tell but water is always a challenge.

I got this unit awhile ago. Initially it was working flawlessly, but now its modes don't seem to be stable. Sometimes it will be in spray mode, pushing down on the button will switch to stream but will only stay in stream mode when the button is pressed, letting go and it will either switch back to spray mode or it will just allow a little trickle of water coming through.

Update
After chatting with Zoey, a representative of Hotis home, she sent me a replacement head for the faucet, which fixed the problems that I was having with the unit, which is now working as expected.

I have a few issues with fitting things in the case - so far the only issue I have with it.

It was somewhat easy to install. You must attach the plate securely before attaching the seat and then may have to adjust a few times after (removing seat, adjust plate, then put seat back on). The bolts were a little tough to get to but I have small hands so was able to maneuver OK. Also, the connection to the bidet wasn't easy to complete. I also ended up having to use plumbers tape since that connection was leaking once the water was turned on. Another reason for 4-star is that the lid doesn't sit completely up, it's almost leaning, but i haven't had an issue with it falling yet.

Not as easy to install as I'd hoped, but with an adaptor purchased from Lowes and heavy duty Teflon tape (due to the plastic parts leaking) this is working out nicely and the water is good.
