Product summary and comments by Red Roulette

Summary:

If you don't have a glass dildo - or want to move up to a larger one - this is an excellent choice. As a 'package,' it's very complete in terms of size, shape and styling.

Product code: F1247100

• Material / Texture

  Material:

  Tempered glass

  Texture:

  Smooth

  Safety features:

  Non-porous / Phthalates free / Hypo-allergenic / Latex free

  –Red Roulette's opinion

  The cheesy packaging decries the simple elegance of this product. It's smooth, slick and seriously sexy. The glass is absolutely rigid, but doesn't feel delicate in any way. It has a good weight to it, too, which is vital in rigid products like this.
  
  The glass design has tons of advantages. For a start, it makes penetration much easier, you can use virtually any type of lube on it and it's a breeze to totally sterilize the shaft - making this a toy that's ideal for sharing, or using both anally and vaginally (as long as you wash it between orifices.)
  
  Of course, being a glass toy, it's entirely rigid. Some people might prefer the realism of a rubbery dildo, that feels more like the 'real thing.' If this hardness works for you, though, the rest of glass's advantages make it an excellent choice in sex toy material.

  –Red Roulette's opinion

  This glass dildo is simple and elegant. It's not obviously phallus-shaped, meaning it's fairly discreet even if it's left in the open (unless you hang out with fellow EF reviewers, who are going to identify it instantly!)
  
  The size is what I can only describe as 'meaty' - it's a fairly intimidating size, but that shouldn't put you off as the smooth glass texture makes it much easier to 'install' in an ass or pussy than a similarly sized cyberskin or silicone product.

• Performance

  –Red Roulette's opinion

  The best thing about this toy? The whole package, really.
  
  It's a very satisfying size - and perfectly proportioned for vaginal penetration or slightly more ambitious anal sexy. The way every knock and vibration resonates through the glass is simply DELICIOUS. If you ever wondered about the appeal of sterile-looking glass dildos, you'll 'get it' when this object's finally buried in one orifice or another.
  
  All in all, it's a very satisfying package that's well thought out and provides an excellent introduction into the world of glass dildos. It's a great FIRST glass toy to buy - but based on its performance, it won't be your last.

• Care and Maintenance

  Care and cleaning:

  Microwave safe / Dishwasher safe / Boilable / Bleachable

  –Red Roulette's opinion

  It's a BREEZE to look after this dildo. You can clean it with soap and water, or clorox, or stick it in the dishwasher, or basically do ANYTHING to it. You can use any type of lube - silicone, oil-based or water-based - with impunity and as long as you sterilize it properly (which is as easy as cleaning crockery) you can share it with whoever you'd like.
  
  The glass is sturdy and rigid - I never felt like it would crack or shatter - but due care is warranted. Obviously, don't fling it down onto the kitchen tiles, because it's not indestructible - but it will CERTAINLY tackle any punishment your ass or pussy can dish out.

• Packaging

  –Red Roulette's opinion

  The toy comes in a straightforward box, with a rigid styrofoam casing to protect it. The box is about the same size as a bottle of wine. The packaging isn't terribly attractive - dollar store typeface which proudly boasts that it's 'hygienic' - but is a good size for stowing away, mailing or hiding under the bed.
