Background. My wife has debilitating chronic pain from failed back surgery and nerve damage. We know from experience she can gain some reprieve from the physical muscle and joint tension pain that is a symptom of the nerve pain. We are in a rental house and it did not seem too feasible to do a big renovation, even though our landlord would allow it, without first trying the likes of this unit. I think we have a low-cost winner untill we build our own home with a proper therapy tub. First impressions - First use: Packaging: 3 out of 5. Minimal waste. Though did (as per usual) have a few pieces of unneeded plastic bags wrapping parts and cords. Design & Features: 3.5 out of 5. -Heater/Warm Air is not that warming. Not sure what should be expected as there are NO details in the manual or on the manufacturer's website regarding this feature. Only that, "Built-in Heater Creates a Soothing & Warming Experience". We started with very hot water and the tub cooled quite a bit in 20min. -Would be nice to have the hose attach so as it is received horizontally on the mat as an option, but this is minor. -Only five double-sided adhesive plates come with this. Could use a few more as replacements or to use in addition to. Not sure where I would buy these from. -Aromatherapy option is a neat touch and works well with a quality essential oil. -On both speeds, it has a lot of power. Lots of bubbles. Better than expected. A variable speed option would be awesome if the manufacturer had a new version in the future. Noise: 5 out of 5. We have had two similar store brand units that were far noisier. It is MUCH quieter than the jet tub we had in our previous home. I don't think it is possible to have the unit quieter unless it was housed in a secondary, vented, sound dampening box-- which I was prepared to build if needed. It is not needed. Those that gripe about the sound either have a defective unit or have unreasonable expectations. A good budget system as far as we can tell with the first use. The alternative is $700-1200 for a tub and $500-1000 renovation, so... ya. If anything changes in the next year of use, I will update this review! UPDATE 07/23/18: During the first use, the suction cups were not holding well to the bottom of the tub. We have a textured acrylic bathtub, so it is understandable there is no good suction adhesion. My wife applied the supplied five pieces of 3M 9448A tape that comes with the unit. Unless it was not applied as per directions (she is sure she did), they also did not stick to the tub. I think I know what happened, but can't be sure until I try again with new tape. Consequently, without good adherence to the bathtub, the whole mat wants to float and move about... one has to attend to it while attempting to relax. After several emails back and forth with the manufacturer in the USA, I have requested and purchased ten of the adhesive pads for a whopping $35+ CDN dollars, shipped from the USA! Why there was only five in the package, to begin with, is beyond me. Even if they did work, it is something that would have to be replaced after several uses, I think. I have found the 3M 9448A adhesive in 10cm pads and roles of tape (on Amazon) for much cheaper, but I wanted to replicate the original setup first to see if the fault is in our installation or just an inadequate adhesive for the purpose. It should be noted, nothing on the 3M website featuring the datasheet for 9448A indicates use with water or being able to repeatedly use in wet conditions. Such a small thing, these pads, but for anyone with a textured or antislip tub bottom, this is critical to the usability of the entire system. Again, why only five in the box? I will update once we try again. Feels like a dang junior high science experiment now! :P UPDATE 08/31/2018 Dropping this down to three stars. It will not adhere to our tub which is acylic and textured for anti-slip. It turns out, we are simply NOT able to use this and we burned $120 on it. If you have a smooth bottom tub, four stars. If not, do not buy it.
