At first glance, it seems like an aircraft motor or microphone and the thought of inserting your penis into one of them must not be inviting for some of men.
It is intensely powerful male stroker with 30 functions of intense vibration, pulsation and escalation. (It is written on the cover, I think it is not that powerful) It is made of body safe, unscented, phthalate free material and 100% waterproof which allows you to use the masturbator in bath. Actually it is better you use it under water so that you can avoid the noise of the ''powerful vibrations''. It is battery operated with 4 AAA batteries which is, in my opinion, another drawback for this masturbator. The battery section at the bottom of the product is not user-friendly. If you try to take the batteries out you will probably see them on the floor due to the absence of a stopper or an extra attachment to hold the batteries on.
The stroker has 22.75 cm x 9 cm for overall and 12 cm x 7.5 cm for sleeve in dimensions. There is removable textured sleeve in it for easy cleaning(Finally found a pro to mention). Besides, it has suction cup swivel mount for hands free multi-positional stimulation and the memory chip enables you to resume on last function used.
I believe that we have more favourable masturbators about than this one.
Sorry Apollo you could not fly me to the moon for this time!
