Update: 6/23/2020 The seat broke. I skimmed another review with pic and funny enough, that's exactly what happened to mine. The hinge pin is a plastic rod seating inside the metal hinges. What was when my 2 yr old shifted while I picked her up and I caught her in a strange lean..she didn't fall off or hit the wall but I heard a crack and the seat was wobbly. When I took it apart, I found the same thing happened as one other reviewer. The plastic rod inside broke in 2 places. That is the weak link. This may be something to consider if you have a heavier household. Maybe she just torqued it the right way or what but it broke. There is no way of repairing it without going through heroics. Guess I will search for another one. Original review: If you have toddlers and are in the potty training phase, child/adult seat combos will be so very convenient! I hated unpacking or having unsightly potty add-ons (especially if you're trying to keep as clutter free as possible). This is one of your solutions. SO let's get to it: Pros: - the build quality overall seems decent - the potty seat fold up and pretty flush with the lid so it doesn't protrude - potty seat has a good magnet, doesn't fall when you put the adult seat down - good balance of weight material. Not flimsy like plastic seats (including plastic soft close) but not super heavy like other wooden seats - easy enough to install - good finish and contour on the seats. Not like the cheap brick mass contractor versions at the major hardware stores. - solid enough hinges but of course, it's still early on Cons: - No instructions?! I DIY so I can figure it out but just to give you a heads up...as some other reviewers mentioned, no instructions. Simple and straightforward, perhaps? It does have different parts than your typical toilet seat kits so I can see why it would take someone a sec to realize what's up. Just in case, I put instructions on the bottom of the review. - My biggest gripe, supplied long screws yet only a few turns secures into the chrome hinges' base? I take more comfort having at least one more turn but we'll see how that holds up - the screw is literally a huge grub screw. No real way to grip it except with grip glove, grip pads or a wrench (which will mar the threads). Good thing is you really only need to hand tight - don't think the hinge is actually metal, more like hard plastic with the chrome finish - not thrilled about the locking nut concept either. It has a disc with 2 different shapes, make sure the deeper bowl is "down" where the threaded nut will fit in and conceptually squeeze the 4 prongs together as it tightens. You'll see what I mean. - updated: hinges have plastic rods inside. You are fine normally I guess but heavier people or people who plop or shift alot on the seat will probably crack that rod faster. Install: There are white plastic/urethane? grommets so what you do is to make it easiest is: (after your old one is removed) #1. before positioning the seat on the toilet, screw the screws into the hinge (not many threads go in so it will be a quick few turns. I recommend a grip pad though sometimes it can hit tight threads and you won't get grip. You want to seat the screw as much as you can. Avoid wrenches, you'll just strip or bust the top of the hinge if you thread too much. Hand tight stop, that's all you should need. a few solid turns or so. *you have been warned* #2. slip the white plastic/urethane? grommets (or spacers) past the screws to the base of the hinge and seat it #3. guide the seat, screws and hinges onto the toilet and through the mounting holes #4. slip the disc up onto the screw from the underside of the toilet *** make sure the tapered side is facing the mounting hole and deeper "bowl" side is down where the nut will contact it #5. hand tighten the nut, probably shouldn't go crazy using an adjustable wrench #6. make sure seat is secure with no wobble side to side. If so, tighten more. Make sure the grommet and hinge base is flat onto the top of the toilet and not crooked over the mounting hole. Done! Overall, would I buy it again? Perhaps. The deciding point was the metal finish on the hinges which matches the decor. Otherwise, there are others I did consider but with white plastic hinges which isn't necessarily a bad thing, just this one was more aesthetic. I'll update if I begin to get wobble or something breaks. FYI, we are average height and weight so let's see how it holds up. UPDATE: 2/13/17 still holding up. Had a variety of people over the months and only a couple times I noted a slight move so I checked the top knob that anchors the seat, it only needed a re-snugging of not even a quarter turn, if that. Otherwise, it has held up remarkably well. It is even the topic of some birthday parties LOL - parent-life. When the ingenious idea of having a 2 in 1 seat ranks right up there with social events. LOL. It is a hit though. The chrome finish has not pitted yet even with some splashes and cleaning solutions. Update 1/2019: I should've written this a few months ago but the kids wouldn't give me the spare time. I love Children's Benadryl - Just kidding. Anywhooo...The finish is holding up considering this was in constant use with my now 5 yr old boy so that's impressive. However, I did notice that maybe it was the combination of adult using this as well, the hidden magnet is starting to crack through the wood finish. For example, you know when you've been in the house long enough that the nails beneath the drywall (from the house flexing in seasons) begin to push the nail and wall material out to like a bump or even punched through? I feel the flexing from various weights make the area around the magnet in the lid do the same thing. It hasn't fell out or anything but the stress cracks are visible. I will try to update with pics later. Asides from that, the seat is still functional and looking good topside. Still a decent solution from not having a plastic singing potty hanging out in the corner somewhere.
