I have sooo much to say!! I have read a lot of these reviews so I basically knew a couple things up front: 1) If the floor of your tub is in any way textured, the suction cups won't really all stick, and 2) If you stay in it long enough, the water will cool off quick due to the cold air bubbles. Check and check! Why didn't any of you momofomos warn me about the dangers of adding bubble bath, though? My friend, Tamara (yep, using her real name), who recommended the device to me didn't warn me, either, so now I think differently about everybody. I had to climb from out of the wall of bubbles to call her so she'd know what to tell the paramedics if it came to that. Anyway, I'm going to do what nobody else felt was pertinent and that's state loudly: DO NOT USE WITH MORE THAN A TABLESPOON OF BUBBLE BATH! That might even be too much. The pic I added is at half mass of what it got to before I could turn it off. What was supposed to be a relaxing experience was borderline terrifying and nobody wants to die of asphyxiation by bubble. To make matters worse, all of this happened on regular speed. I tunneled through to the remote stuck to the ledge of the tub to try to turn it off and it goes QUICKLY to jet propulsion!! There is no hesitation in the switch in force. Stopping it takes non-panicked precision. One too many presses and it's back on regular and there's no getting to stop without once again going to mega-blaster. Sure enough, there's the faintest amount of texture on my tub floor so only four of them stuck, but that didn't matter because body weight holds it down well enough. And I only bathe in scalding water so I didn't experience the fast cooling down of the water effect. That's mostly because: 1) Due to bubble wall building, I couldn't run it longer than two minutes at a time, 2) When you're in a heightened state of alarm, it felt like the hot water got hotter, and 3) If I'd have just let the bubbles run amok, they'd have flowed down my street and scared the locals. Therefore, I just feel like if you start off with water that's adult female hot (hotter than the level of heat men can withstand) and not toddler warm, you should be able to enjoy a decent period of action without losing heat. Or leave enough room to keep adding new hot water. I'd be snippy and day, "Duh, it's not rocket science," but shoot, I almost died behind two capfuls of Dr. Teal's bubble bath so maybe there is a science course requirement after all. That didn't come in the box or manual, either. And I read the manual because it told me the remote doesn't work unless the power is turned on at the machine. Alas, I should have known better but I fought the hard fight and survived to write this warning...ahem, review. What I did experience was pretty amazing...the bubbles were strong on regular and very strong on 2nd speed. It's easy to set up. My bathroom's kinda large so I had to run an extension cord but the cord on the machine itself is nice and long. There is a reset/surge button on the plug, so that's a great feature. The mat is easy to spray to clean. I already feel like, sans bubble bath next time, I will be able to more thoroughly enjoy this product. There's nowhere to go but up from here, anyway, right?? I am giving it a 4.5 (4 on the Amazon scale) out of 5. I'm sleepy right now and I'm not sure if it's from coming off my panic high or the fact that the time it was running, it actually worked out the little muscle kinks from my workout. I bought this as a surprise gift for my hubby for when he gets home from doing the hard work of Hurricane Ian Recovery & Restoration in FL. I was just trying it out to know all the ins and outs. And now you know, too!! I recommend this product. Be careful removing the mat where there is strong suction so you don't tear the mat. And remember, don't use too much bubble bath.
