This is a nice product and I’ve used it a lot. Really very simple to figure out how to operate and has been great relief for my feet. There are some things that you need to consider when buying this product.1. This unit is heavy, much more heavy than you would expect. Be prepared for that. The weight makes it harder to move around; this isn’t a deal breaker but you do need to plan for this.2. The handle works fine, easy to adjust.3. Buttons on the unit are intuitive and it takes little effort/experimenting to figure out. The remote control works but, isn’t that nice; but, really, the controls are on the unit, are between your feet, your setting in a chair so, it takes little effort to reach down to adjust/operate.4. I’m not a big person but to think you can use this for your caves may not be realistic. I can’t reasonably get my caves to fit into the massage area. I have no need to message my forearms so can’t give feedback on that part.5. Everyone’s feet are different; length, arch, width and so on. Be prepared to experiment; there are two sets of rollers per side and the only way I can get the most from them is to place my feet in different locations to get to sore areas. Just know at least for my feet, there isn’t a single location to maximize massage.6. The air compression on feet comes from the sides, depending on the position of your foot you will have to adjust compression up or down. For example, when my feet are down/lower in the openings I have to use a lower compression setting but, when my feet sit forward/higher in the openings I can go to a higher compression setting.7. Finally, this is not a cheap product in construction or cost. It is well made and carries a price that reflects that.
