Girth, Vibrations, and Texture - Oh My!

The Maximus Rider Penis Girth Extension by Cal Exotics is a great design for those who want to gain queen-sized girth, but can be too snug for some and creates a numbness making love-making uncomfortable. It does have a ribbed shaft that feels amazing if you can handle the girth, but the vibrating bullet is lacking. Not a product I feel can be enjoyed by the general toy-lover.
+Great ribbed texture
+Provides queen-sized girth
+Comes with replacement batteries
-Vibrations do not work great
-Attracts lint and hair
-Fits a bit too snug

extremely useful review


The Maximus Rider Penis Girth Extension by Cal Exotics is a multi-functional penis sleeve in that it adds girth to the penis, is designed to help maintain an erection, and has a vibrating attachment and ribbed texture that are designed for stimulation. Due to the fact that it is designed to fit onto the penis, this can be used during vaginal or anal sex. There is a vibrating bullet at the base of the sleeve that can stimulate the clitoris if worn traditionally or it can stimulate the perineal area if worn upside-down. Besides couples using this to enhance their sex lives, this product can be used during solo sessions. I have found that this extender is also great to use on a vibrator, just use a little lube to help slide it on. It can add that extra girth that is needed to a traditional vibrator that is lacking a bit in girth. Also, the ribbed texture gives you the option to take a not textured vibe to the next level. Due to the design of the extender it does add quite a bit of extra girth to a vibrator or, as intended, a penis. Be forewarned, this extender is going to make things more intended for queen-sized users. I would not recommend this for beginners.

Material / Texture

The Maximus Rider Penis Girth Extension by Cal Exotics is made of TPR (thermoplastic elastomer), also known as TPE. TPR has a safety rating of 7. TPR is more porous than silicone, so it is recommended to use a condom or only use with a fluid-bonded partner. It is safe to use with both silicone-based or water-based lubricants. There is not a very noticeable odor to it when it is initially opened, but there is somewhat of a synthetic odor if you hold it close to your face. The Maximus Rider is available in Cobalt or Clear. It is extremely flexible due to being made of TPR.

One of the best features of this product are the different textures. Along the shaft of the sleeve it alternates between smooth and ribbed textures. These ribbed rings are not just just little lines on the shaft. They are nice, raised, large rings that you will definitely feel when using this sleeve. Also, on the front of the bullet where it makes contact with your partner, there are little nubs to add to the stimulation provided by the vibrations. The downside to the textured shaft made with TPR is that it does create a bit of drag when used, so make sure you really lube it up well when using, especially since it will create quite a bit of girth. One major negative part of the sleeve's material is that it attracts every bit of hair and lint in the air around it.

Shape / Design / Size / Fit

The Maximus Rider Penis Girth Extension is shaped to a small, girthy vibrator that has been hollowed out and had the tip cut off. It is not a tube like a toilet paper roll. It is hollow to accommodate the penis and even has the end shaped to fit around the head of the penis properly to accommodate a penis/vibrator up to 6 inches in girth. The extender is 4 inches in length, 1 1/2 inches in diameter, 1/4 inch in thickness, and about 3 inches high when including the vibrator. The sleeve weighs approximately 0.2 pounds. Due to its obvious shape I would not describe this as a discreet product.

The sleeve is intended to add girth to the penis of the wearer, help maintain their erection, along with providing stimulation through the ribbed design of the shaft and the vibrator that is attached on top. The vibrator is designed to have two functions. It can either start vibrating upon contacting the front nubs of the bullet or it can constantly be turned on. There is a very small switch on the back that can change the settings. I preferred to leave it on constantly. The sleeve itself fits very snugly onto the penis or the vibrator. There was definitely no risk of it falling off either of them. Due to the snugness, it was a bit difficult to pull off of my husband's penis, but easy to pull off of the vibrator since I did not have to worry about it snapping on it or pinching.

Functions / Performance / Controls

As I said, the sleeve is intended to add girth to the penis of the wearer, help maintain their erection, along with providing stimulation to the wearer's partner. This product more than succeeds in adding girth to one's penis or vibrator. It will be sure to turn a penis or vibrator into a queen-sized lover's dream come true. I could insert the sleeve if it was on the vibrator while taking it slowly, but when my husband wore it, there was too much girth and we could not get his penis in. Also the textures along the shaft feel great and a great stimulation. As for helping to maintain an erection and the vibrating bullet, this is where the product is lacking. My husband said that it cut off circulation, made him feel numb while he was wearing it, and felt like it was weighing him down. As for the vibrator, it is easy enough to switch the settings even when wearing it, but the clicking noise that the bullet makes to provide the "on contact" vibration is very annoying and does not work as well as it was intended to work. The vibrations are not very strong, perhaps a 1 1/2 if it gave me the option and it is very buzzy and loud. One positive with the vibrator is that it does come with replacement batteries.

Care and Maintenance

Cleaning the Maximus Rider Penis Girth Extension is very easy. Just use warm water and a mild soap, but be careful to not wet the bullet since it is not waterproof. TPR cannot be boiled, so please do not do so. As noted above, this thing will attract all lint and hair that comes near it. I recommend keeping it in the plastic bag that it comes in. In short, it is easy to clean, but not to keep clean.

The packaging is not discreet at all. Looking at the package you will know what this is if you can read. There is a plastic bag inside the box that contains the sleeve and the extra batteries. So rather than describe all of the text on the package, just look at the pictures below.

Follow-up commentary
Since my initial review of the Maximus Rider Penis Girth Extension by Cal Exotics I thought I would give it one more chance to wow me. Maybe the week I tried it was just not a good week for experimenting for me or maybe I wasn't being creative enough. So, I gave it one more shot on a day where I was dying for a little "me time." I started with some light teasing stuff that got my pulse racing and made me ready to be filled with something to take me over the edge and then... the annoying clicking started again. Every time my hand might hit the sensor or it would hit my "mound of desire", click, click, CLICK! Not to mention the buzzing noise. While the extra girth was a little nice, I tossed aside my vibe that I had the extension on and grabbed an old and faithful friend. The Maximus Rider Penis Girth Extension by Cal Exotics is just not for me.
