This is a toy that was provided free of charge by EF for subscribing and I think it was an excellent gift and value. Not only is it waterproof, but is powerful too. It is a great plastic standard waterproof vibe ideal for beginners mostly, but has it's uses for even seasoned toy users. It is a great shape for vaginal or anal stimulation and can hit a G spot if need be (unless you really require a lot of bend).

I think this is a great beginner toy for those who like buzzy vibrations. I think best for clitoral/external stimulation, but is a nice size for penetration. This is a good introduction to vibrators. Once we got hold of a Lelo, though, this has sat idle, but could always be a go to for shower/bath play, if we ever needed that.

It's a good toy for couples as well and the little head is ideal for teasing nipples, besides the clitoris.

The Blueberry Bliss is made of hard smooth Plastic which is an 8 on the safety scale. It is hard and bulbous, which can be felt upon insertion and thrusting.

If you might be sharing or swapping between anal/vaginal use it is always a good idea to use condoms as a cover, just in case. Plus it makes for easy cleanup after anal use.

Blueberry Bliss is semi transparent plastic Blue 6 1/4" in length, 5 1/4" insertable with a 3" circumference or 1" in diameter. It's about a standard vibrator size with a multi-width bulb tip. It weighs about a third of a pound. The shape is semi-realistic and is suitable for vaginal or anal use, as well as all over body stimulation. The tip works nice for teasing or intense clit stimulation.

It is neither discreet or travel friendly. You can see the inner workings or the vibrator within, but it's not so transparent that it screams invisible. In lower light you have to look fairly close to make out any details within.

Blueberry is a variable speed vibrator. Just turn the dial at the base to turn it on and continue turning clockwise to jack up the vibrations. At full power it is pretty impressive in a buzzy way (not rumbly).
It is advertised as waterproof and I don't question that, but I have not put it to the test.

The vibrations are mostly centered in the second bulb (you can see the motor inside), but can definitely be felt in the tip and down the shaft, but not so much that it numbs your hand or anything.

Noise wise, it is fairly loud, but not off the charts loud. I'd say you could discreetly use it under the covers without being heard through a door/wall.

It is simple to use and batteries seem to go a long way.

Runs on 2 AA batteries.

This is compatible with any type of lube if you need it. It washes with soap and water and being waterproof makes it a cinch to clean.

I store it in a drawer or shoe box with other toys. No special care required. It is always a good idea to take the batteries out when in storage for extended periods.

The only packaging was a small plastic bag that contained the vibrator. The packaging was recyclable.

We used this toy quite a bit before discovering the Lelo LIV, which has permanently usurped the role of blueberry Bliss. I will keep it around and ready for anytime we might want to need a vibrator in the shower or tub though, just in case the need arises.

While we used it, we did enjoy it a lot. It was quite stimulating and powerful. Considering we got it free, it was a great gift offering. I wouldn't hesitate to recommend it as a cheap waterproof vibe for a beginner though.
