The device is appropriately sized for an intimate massaging function. It has smart, ergonomic design that affords comfortable and reasonably secure handling. The medical grade silicone offers a nice tactile feel, plus allows for easy cleaning/washing.It has a silicone loop/tether attached around the power button. I appreciate that the loop can be easily removed, so the user has a choice whether to use it or not (I personally feel that it’s better without the loop).Operation is very easy and intuitive. One button atop the device is the sole control. It powers the device on, with subsequent presses accessing the three power intensities. After the three strengths, another press powers it off. Simple control procedure.You may notice in the product details’ pictures that the massage surface is not flat. Indeed, it’s designed to be asymmetrical. This provides options in terms of surface feel. You can get a softer, ’squishy’ application, or use a firmer surface. Or, you can alternate! It’s just a matter of angle and positioning of the device.For a small device, it contains an ample battery capacity, providing about 1.5 hours of operation when using high intensity setting (longer operating time if lower intensity is used, of course). Charging time, per the user manual is 2 hours.Attached are photos to show real world images, with a ruler for size reference. Various angles are shown for a good overview of the design shape and appearance of the massaging device.I feel this personal massager fulfills the intended functions, with smart design and quality materials and manufacture. It merits a 4.5 - 4.75 star rating, with a very high level recommendation.
