Master Series Three Bumps for Your Rump Butt Plug Large

Bottom line: It's big. Very big. Better quality than expected, great product overall despite minor imperfections. Good price for a lot of fun. Very worthwhile line of products - just get the right size for what you need! Can't recommend it enough.Dimensions (LARGE model):The bumps are (circumference) first 8.4", second 9.2", third 10.9", or 2.7" / 2.9" / 3.5" thick. Insertable length is 10". If you're just mastering the medium, and unsure if you can handle the large, try the Doc Johnson American Bombshell B-10 Tango first. The B-10 Tango is noticeably smaller, the angle on the bumps are gentler, and it's another great product. I think it's the logical step up from the Master Series Three Bumps for Your Rump Butt Plug, Medium before moving on to the THREE BUMPS LARGE.Pros:- Way better than expected. I planned on buying it, and was really expecting an ugly, cheap, low quality toy. But it's not. The challenge is great and the image doesn't do the product justice.- Material is surprisingly good. No burning sensations. Smells like grape. It's not the plastic "toy smell" that is common with less expensive toys.- Slick material, with some give. Bumps may "mushroom" / squish under pressure a bit if the bumps are a challenge for you. Toy is strong enough to free stand, but it will bend with pressure. A guiding hand is pretty much necessary. I find this level of softness / flexibility a good thing.- Suction cup is plenty strong. Will hold onto walls, but isn't too hard to remove when you want to.- Challenging: to get the whole thing you'll need to be able to get two things: the top bump (8.5" circ / 2.7" thick) at least 8" inside, while simultaneously getting past the 10.9" circ / 3.5" thick bottom bump. It is not easy.- Cost: this is a a great value.Cons:- Minor build imperfections in the surface of the product. There's a couple tiny spots on the surface of the toy which are likely from small air bubbles in the mould. They are in non-critical spots (one on the underside of the top bulge, the other on the neck between 2nd and 3rd bulges) so they don't really impact use.- Length / size of gaps / steepness of bulges: I would prefer the item to be slightly shorter, just a bit. Shorten the gaps between bulges slightly, and make them slightly wider, and you'll have a shape with slightly more gradual of bulges without a too-deep toy. It's pretty good as-is, I just feel it'd be slightly better if it were an inch shorter with slightly thicker 'rest stops', more like the Si Novelties Bump Plug, Black, X-Large, 12.64-Ounce.- Not really a trainer for width: don't buy this expecting to train you up from the second bump to the third. It's a huge jump in size between the two. If you're at the 9.5" circumference / 3" width range, jumping up to the almost 11" circumference / 3.5" range is a big step. The neck between the second bump and the relatively rapid growth of the third bump means the toy doesn't slowly open you in a way suitable for training. The B-10 Tango is more gentle, but not really a trainer either.Items to consider for training:The Doc Johnson American Bombshell Rockeye is a great trainer up to the 10.8" circ / 3.5" thickness.The Doc Johnson American Bombshell B-10 Tango is sized between the THREE BUMPS Medium and Large. The B-10 Tango is 2.75" / 3.0" / 3.25" thick, so the bottom bump is smaller, which might help you get ready for the challenge.The Doc Johnson American Bombshell B-10 Warhead or Doc Johnson American Bombshell B-10 Torpedo have similarly sized 'tips' that can go to similar depths. Alternatively, if you can go deep on Pipedream Products Basix Rubber Works Fist of Fury, Black or Belladonna's Bitch Fist, you should be fine for the depth aspect of this toy.Regarding width, the Si Novelties Goose with Suction, Brown, Large, 62.56-Ounce, Doc Johnson American Bombshell Shellshock, Large, Gun Metal are good options to prepare for the (near) 11" circumference. If you can afford to go to Amazon.com and pay the shipping, something from the TSX toy lineup such as the "Bed Knob Buddy Large" (10.3" circ) or Tsunami Dong Red (10.5" circ) are good pre-11" items.

Having all three, small, medium and large. Small is great and manageable all three bumps. Medium is a great transition up from small, that second bump is noticeable, getting to the third bump took some times, but wow once it was in. Going to large, even the first bump from being able to handle all of the medium is wow. Managed the first bump on the large the first time, and it was an eye opener. When it’s in, it’s in, don’t try to pull out while exploding. You can tell these are for the experienced, very few videos out there, where these great toys are front and center. Great for any toy collection.

I like the size, shape and weight of this toy. What I do not like about it is the suction power of the base. My shower is 12"x12" tiles both walls and floor. This thing refuses to stay stuck to the wall for more than 5 minutes before falling to the floor where it invariably sticks with "SUPER SUCTION POWER" for days on end. The first time it fell off the wall unexpectedly it landed on and broke my big toe so be warned that this toy can hurt you.I've tried cleaning the base, cleaning the wall, lite pressure, heavy pressure, heating both the top and wall, Poligrip, everything but superglue to no avail. Since I have other toys made of the same material, are lighter weight and have a larger suction hollow that stick in the same spot without any issues so I believe therein is the problem.

I do not like that the suction cup on the bottom was defective it has a warp at the bottom of the suction cup which makes it impossible to use plus the toy itself has a raised seam and is lopsided I am thoroughly disappointed what a waste of money I have been 100% ripped off

This has become my favorite toy. I'm editing my review to reflect months of use. Beware, this toy is HUGE. I'm a size queen, and it is still a large toy. It's still one of my favorite toys. The bumps are the perfect addition to any toy, and the way they pop in, is the most amazing feeling. I use it for both anal and vaginal play. Vaginally, it hits my gspot over and over, and has made me squirt for the first time. I use a water based lube, and it's necessary. There is kind of a suction base on this toy, enough to hold it in place while you mount it, but I've found it will release with any rough use. Anally, I can only take the first two lumps. Not only is it wide, and stretches me almost as much as fisting, but it is long enough that I am unable to get it any deeper so far. If you are into big toys, this one is an absolute must. I've read other reviews, saying it smells. I have not experienced this at all. It has a great weight to it, it fills you up, and it massages every single spot. I love it so much, I ordered another one just in case.
