My verdict

This toy is absolutely so fun to use! I highly recommend it to those who are into monster dildos. The price is very affordable and easy to access. The toy comes with everything needed to play, except cum lube. It even has an extra pump in order to help clean the ejaculation tube after play. My biggest concern would be that the manual pumping may be hard for those with mobility issues in their hands. All other issues are minor and to be expected with the kind of toy that it is.

Pros

Ejaculating
Expanding
Comes with XL Syringe
Knots

Cons

Hard to clean ejaculation tube
Suction not very strong/Top heavy
Tubes can get in the way

Design

Powerful and Huge

This toy was fantastic find. It covers both monster cocks, ejaculation, knotting and expanding. It was an absolute winner for me. I bought the medium size. The toy itself is 9in (22.86cm) total in height and insertable 8.5in (21.59cm). With the knot fully expanded, the toy becomes 9in (22.86) insertable. The width of the tip is 1.5in (3.81cm). The knot is about 3in (7.62cm) around, and the expanding knot can be as big as 5in (12.7cm) around. The dildo has two tubes attached to it. One is for the pressure pump, and the other is for cum lube. They are not detachable so at times they do get in the way and can be cumbersome to deal with. The inflation tube is about 3ft (0.9144m) and the ejaculation tube is about 2.9ft (0.88392m). The set comes with a XL 100ml syringe and a separate pump that is used during cleaning. I found the design to be well thought out and the extra products very beneficial.

Quality

Well Thought Out

The quality of the toy feels pretty nice. It has good flexibility and also sturdiness to it. The pump attachment and the syringe fit the tubes very well and do not have issues using them. The giant syringe is a great feature and helps with making the ejaculation play easier. The inflation tube is also labeled for easy use. While inflating the knot, there is a limit to how big it can get. It is easy to find that limit when playing, as the pump will deflate or a second and also will no longer inflate the knot. I find this feature very helpful when in the mood, as one might not be as mindful about how much the knot is inflating.

Experience

Amazing and So Filling

With this toy being 9in (2286cm) long, it is a lot to take in. I was able to take it all the way once. The expansion of the knot was a really nice feature. It made the toy feel more filling, but I also kind of wish the top knot inflated for when I can't take as much. Also, the toy is very top heavy, so the suction is not the strongest. There are times when using this, either on something stationary or on a machine, that it will unstick. The suction will not stick to anything textured, so I suggest using it on a smooth flat surface.

The actual experience of using the toy was phenomenal. It was perfect for getting in the monster fucking head space and the expanding knot really made that come to life. The toy is on the bigger side so that made the stretch feel even more intense. I am allergic to cum lube, so I have not used the ejaculation feature with anything other than water. The syringe is very big so it can hold quite a bit. I would say that one would need to use about three of the XL size syringes for true cum flooding. The syringes are easy to find and buy on Amazon, so it should not be difficult adding more to the collection.

Performance

Sometimes Cumbersome

I do not have any issues with the tubes disconnecting, but I do have some issues with the tubes getting in the way. Sometimes, I need to move the tubes around in order to get situated on the toy. This is to be expected, and I do not find this issue to be a major flaw in the toy design. The pump is a basic pressure pump like what is on manual blood pressure cuffs. It is very easy to use and figure out. With the toy being top heavy, it can have issues falling over while in accelerated use. This is a common factor with longer and larger toys, so I suggest just keeping the tip in while thrusting.

Materials and care

Both Mediocre and Hard to Clean

Cleaning the toy without using the ejaculation part is fairly simple. The whole toy is waterproof, and one can clean the entire thing. Something to note is that the tubes do not disconnect and they can get in the way a little bit. As for cleaning the toy with the ejaculating feature, it is very tedious and cumbersome. An important thing to remember is that it is imperative to fully clean and dry the ejaculation tube, so that there is no mold build up inside. With that said, it is a tedious task drying the tube once it has been flushed out. The bonus part is that the set comes with an extra pump to push air through the top of the dildo. The negative part is that it is a tedious task and can take about 15 minutes to push all the extra water droplets out. I also can use the syringe to push water out from the top of the toy as well.

Packaging

Simple But Reusable Packaging

The packaging is in a plain long black box. It comes with the toy, an XL 100ml syringe, the pump for the inflation tube and an extra pump for flushing the excess water from the ejaculation tube. The only set up that is required is attaching the pump to correct tube. This is easily done because the inflation tube is labeled so there is no confusion. All of the items can fit in the box with strategic packing. I utilize the box as its regular storage container and that helps a lot.

Price

$35 USD Affordable and Easy to Access

With this product being available on Amazon it makes it very easy to access. I have also included a link to the product at the beginning of this review. The price for the toy after tax is about $35 USD and also available for prime delivery. I find this to be affordable especially with all the features the toy comes with.
