Little Heart

The Lucid Heart is a great warm-up g-spot toy and I will continue to use it. My partner really likes the design because it doesn't look threatening. It would have been a better g-spot toy if it were longer, but others may find it to be the perfect size for them.
Body safe
Curved shaft
Short length
Rating by reviewer:
extremely useful review


The Lucid Heart is a glass dildo that can be used vaginally, and due to large handle can also be used anally if you choose. Glass can be slowly warmed up or cooled down making this toy great for temperature play. I've used the Lucid Heart in the tub and in bed with my partner.

Glass is very hard so be careful when thrusting, as it can bruise your cervix. This all depends on your anatomy though, because the Lucid Heart is a little on the short side. It has a curved shaft and a bulb tip and it works pretty well for g-spot stimulation.

Material / Texture

The Lucid Heart is made of glass and is a 10 on the Eden safety scale. It's non-porous, hypo-allergenic, and latex and phthalates free. There was no smell or taste after being washed, and it is completely rigid with no give. I enjoy that it is very smooth and without texture because I don't like texture on my g-spot.

The temperature of glass is easily manipulated so it works well for temperature play. Just don't change the temperature too quickly because this can cause it to crack or break. To warm up place in a warm bowl of water and to cool down put in a cool bowl of water. Even though extreme temperature change can break a glass toy, it's actually pretty durable. Just be careful not to drop it on a hard surface.
    • Not porous at all
    • Rigid
    • Smooth

Design / Shape / Size

The design is over-all nice. It has a curved shaft with a bulbed tip similar to the smaller bulb on the Pure Wand. One of the things I like the most is the heart shaped handle. It makes it easy to hold onto and can also serve as a way to make it anal safe. It's transparent and the whole design is really cute.

Overall length: 7 inches
Insertable length: 4.75 inches
Circumference of shaft: 3.25 inches
Circumference of bulb: 4.5 inches
Diameter: 1.25 inches

The Lucid Heart looks like a dildo so travel at your own risk. The size is best for beginners to average users. The circumference is definitely lacking for size queens. I love the curve and bulbed end and it works pretty well for g-spot stimulation. My only complaint is that the insertable length isn't what I'm used to so it feels just a little too short.

I like the Lucid Heart, but it's not my favorite glass toy. I think it would have been perfect if it had another half an inch to an inch more to the insertable length. The lack of length is really the biggest downfall for me. The design kind of reminds me of the Pure Wand, but the Lucid Heart is lighter I can play with it much longer.

It has a lot going for it and those who don't mind a shorter length are likely to love this one.

Care and Maintenance

Glass is low maintenance and easy to care for. I clean mine with how water and soap and keep it in the glass/steel toy drawer of my toy box.
There are other ways to clean the Lucid Heart:
- Toy wipes
- Wipe down with 10% bleach solution
- Sex toy cleaner

You can use water-based, oil, and silicone lubricants with the Lucid Heart.
    • Easy to clean
    • Easy to store


The Lucid Heart was packaged in a cheesy black box with bright lettering all over. It kind of screamed cheap so I don't store mine it it and I wouldn't gift it in the box either. There weren't any user instructions in the box but I find that a lot of glass toys don't usually come with any.


This serves as a good warm-up toy for my g-spot. It would have been a main event type toy if only it were a little longer. My partner really likes the handle and an upside to the short length is that he can't bruise my cervix with it. Everyone's anatomy is different so you may want to test it out yourself before you give it to your partner to use on you.

We didn't use it anally because I only really like my thrusting anal toys to be silicone.
