Scepter of LoveThe Rainbow Heart is a beautiful dildo that's as appealing to the eye as it is to the touch. It's handle makes it great for insertion, whether it's being used vaginally or anally. The texture also feels nice when used externally on the body. Since it's made of glass it's easy to clean and retains temperature well.
Although the pyrex glass is smooth, there are very few areas on the Rainbow Heart where the smoothness can be felt, since it's covered in texture. There are over 95 raised nubs on the insertable shaft of the dildo. The nubs are all around the size of a pea, but vary slightly in shape. Some of the nubs are more rounded and others come to a rounded point on one of the sides. The glass between the nubs is smooth as is the handle and the rounded tip of the dildo.
Pyrex glass has no smell or taste. Since glass is so smooth it needs very little lube, if any for comfortable insertion. Lube doesn't absorb into the material during use, so most users won't have to reapply it to the toy. Glass is a great material for temperature play, because it retains heat and cold well. Although Pyrex glass should be able to handle temperature changes, it's not recommended to expose it to extreme heat and then switch to extreme cold. Glass that has been exposed to heat or cold should be felt before internal use, because it could potentially cause burns to sensitive areas.
Glass is an unyielding material and the nubs on the Rainbow Heart make the hardness of the glass more noticeable. The dildo could be considered too intense for some users and because of this it is probably best suited for more advanced users, texture lovers or beginners who are willing to take it slow.
There are a few imperfections in the glass such as tiny bubbles in some areas and a seam along the length of the insertable portion of the dildo. Neither of these imperfections is really noticeable unless the user is looking closely at the glass. There are also a few areas on the glass that divet in as a result of the liquid glass being poured into the mold.
This dildo doesn't exactly scream sex toy, however, it will draw attention because of it's pretty design. Therefore, it is best to store it away in a padded bag away from prying eyes. When it's placed in a padded storage bag it is suitable for traveling.
Glass becomes slippery when lube is applied, but because of the handle it's less likely that the dildo will slip out of your hand during use. However, it's a good idea to wipe lube off your hands before gripping the handle, because that area is smooth and the dildo could potentially slip from your grasp.
