This is perfect for someone without an active partner, as well as for couples that wish to try double-penetration, or maybe one partner just wishes to control it on the other partner. Some safety precautions are necessary, of course. Learning how far the machine can thrust and how forcefully while it is inside you is a top priority. Keeping it clean comes right behind it. As well as being cautious from using electricity.

The toy itself is pretty simple in design. The machine is rather light and somewhat sturdier than you might think. The dildo has some texture, but it is more about the thrusting than anything else.

The design seems a bit lightweight, but that isn't as much a problem as you might think. While you can use the suction cups to position it on a smooth surface, whether that is a table, counter, or floor, you can also easily set it on a carpet and use it that way as well. The thrusting arm can be adjusted in two places to get the angle and height to a more accurate position, that this takes a bit of practice to get used to.

I found the Auto Fuk to work rather well. It took a bit for the initial positioning, but after that, it was easy to control and use. It can be a bit noisy on the higher settings, however, so background noise to cover it is recommended if you need to be discreet. Lubing it was easy, of course, and once the position was locked, it was simply a matter of enjoying the ride.

The toy is silicone, and that means water-based lubrication only. Don't make the mistake of using silicone lube with this, as the results won't be pretty. It isn't waterproof, so don't even think of submerging the main machine. You can detach the dildo, but I wouldn't recommend submerging the connection point itself, or the entire dildo. There is a gap where the dildo fits onto the stiffer core. It wouldn't be a good idea to get water down in it.

For cleaning, I preferred to just allow hot water to run over the end of the dildo via the bathroom sink while holding the end with the connector point. You can wipe it down with a cleaning cloth and toy cleaner, as well as antibacterial soap. Then just pat it dry. Don't use a fuzzy towel, as that usually leaves fibers behind. The machine itself can be wiped clean with a paper towel and toy cleaner if any fluids get on it.

For storage, I found it easiest to just use the box it came in. It is easy to unscrew the arm points so it can fold down tight to the base. Similarly, it's easier to keep the power cord, control box, machine, and dildo all in one place.

I would say the only ones who really should be cautious with this are those who squirt heavily during orgasm. Depending on the volume, there could be a risk of getting fluid down near where the control box plugs into the machine itself.

Of course, there is always a fix for this. It is entirely possible to waterproof the connection point where the control box plugs into the machine. Of course, this would mean the wire would be more permanently fixed into place, but that's not a huge problem. There is a rubber spray on the market, I'm sure most have seen the commercials with the boat made from screen doors or chicken wire, coated in this spray.

I don't believe it would be much trouble to connect the control box to the machine, and then spray this sealant on the cord and side of the machine to allow it to seal over the hole.

But this is just a personal observation. Most shouldn't have a problem with this, and it may be that a heavy squirter may not have that problem either.
