I recommend looking for a high-quality vibrator.Check the quality of the materials used in making the product. If you can, look at them with your own eyes and touch them with your hands. A good material is smooth, sleek and flexible; it won't feel rough to the touch or bend easily when pressed too hard against it. Make sure that any insertable parts don't have sharp edges or other flaws that could cause discomfort during use—and make sure they'll stay clean while they're inside you!Check the quality of construction: Are there seams where two different pieces meet? Is everything glued together securely? Does anything look loose or shoddy?Look at how well each part fits together in its packaging: Is the smooth rose vibrator secure enough not to fall out if you turn it upside down (or toss it around carelessly)? Does everything line up properly when closed up again afterwards--does each piece sit flush against its neighbor without leaving any gaps where dirt could get trapped between them? How big is this thing overall--will it fit into whatever space you plan on storing/using it most often without being too big or too small for where intended use requires extra room availability?
