For small to average-sized users, this toy is great for vaginal play thanks to its very realistic-feeling shape and material. I have not tried this dildo anally, but it is about the same width as my widest anal toy and I'm not a large woman, so I think Mark would work well for a small-to-average user with some anal experience.

There is a little bit of texture on this toy, but to be honest, I don't feel it much during use. For me, the most stimulating aspects of this toy are the softness, smoothness, the matte finish of the shaft's outer material, and the ease with which it warms to body temperature. All of these features combine to make the toy feel very realistic. The silicone is very high-quality and has no smell at all. While it does attract hair, it is fairly easy to clean off with water - not without; trying to pick or brush off hairs is a task. I manage to keep it mostly safe by storing it in a plastic chest with my other toys.

This is a simple. realistic-shaped dildo with a very slight curve. It can be straightened under little pressure, but I have found that it maintains its curve during use. In general, I do not get a lot of extra enjoyment from curved shapes, so Mark's mostly-straight shape works great for me. For those who like G-spot stimulation, the shape might be nice, but if it's a priority, be warned that the curve is very subtle.

The firm inner core lends this toy a very rigid overall structure, which I sometimes find uncomfortable, but I am fairly sensitive and doubt this would bother most users.

At just under 1.4" in diameter, this toy is a great size for me, as I have found even dildos closer to 1.6" to be uncomfortably large. The length is perfect as well. I have another Tantus dildo that, at 7" long, is too long to fit all the way inside me. This one is not too large and not too small. It may work well for some beginning users.

I would not recommend this for those seeking a discreet toy, as it is far too obviously a dildo.

The Mark has a very firm and wide base intended to make the toy harness-compatible. While I have not used it in a harness, I find the base to be a great hand-hold thanks to its rigidity, its round edge, and the material, which, with no lube or a minimal amount of lube, is easy to keep a grip on. Overall, I have very few negative things to say about this toy. The material feels fantastic, the shape is almost perfect, and the quality is high. The size is good for those who prefer smallish or average-sized toys, although for those who like larger toys, I would not recommend this one.

This material is easy to care for, despite its being a hair magnet. I clean it with a regular antibacterial toy cleaner and warm water and store it in a plastic chest of drawers. I own a cat and am constantly surrounded by fur, though, so taking the toy out of the drawer for any length of time almost guarantees that it will get fur stuck to it and have to be washed with water before use.

As it's silicone, I keep it away from direct contact with other silicone, including my other toys and silicone lubes. Although some have said that Tantus silicone is high-quality enough to stand up to some silicone lubes, I have tried the high-quality silicone lube I own on the base of another Tantus toy and found that it melted it, so I can confirm that it is NOT a good idea to use silicone lube on these toys. Stick to water-based.
