Even as an ultra beginner who could never handle such activities before, the first two were too small and the fourth was way too big of a step.The included lubrication product actually worked really well, no complaints there. The silicone also passed the burn test (I took a lighter to the bottom edge of one to see if it would ignite and it did not, it just left white ash which is what is supposed to happen with real silicone) and also the pinch test (it didn't turn white) so it seems to be pure or very close to pure silicone but despite that, it's very hard to clean. I started off with some Castile soap and the smell was still very strong and after cleaning with Dawn it was still there, just a bit muted. I don't intend to share my toys so it isn't a huge problem, just something to be aware of.No regrets buying this product though. For the price, you really can't beat what you get.A little longer than I like but they stay in place and get you ready for bigger and better things.FavoriteThese plugs are literally perfect. I really wish they sold the lube that comes with it separately as well because I would buy a lot of it.They’re decent for beginners, but for some reason, I always need to clean them twice. The material seems to leave behind a white film/dust after being washed. I’ve tried multiple types of soap so I doubt that the cleaning medium is as fault. I prefer glass plugs, but this is a decent set! I wouldn’t suggest using the lube though. I just don’t trust it. I haven’t tried using the suction feature because I haven’t had a need for it. I honestly don’t know if they’d be able to do that or do it well.I started to use this item with the lube that came with it and it works great. I started with the small 4.1in and used it for about 2 hours a day when I get home. Two days later I am wearing the 4.5in and I do feel a great difference. If you are a beginner then make sure that you don't leave it in your anal cavity until your body gets used to it. Always use some type of lube, because your anal cavity is not self-lubricated. NOTE: Once using this great item, make sure you wash them. I use dawn dish soap, with warm water and then let them air dry for about 12 hours when I am at work. Have fun everyone that is being curious on these types of items.OMG! These are just to sweet to pass up, great for beginners and and absolutely perfect for the experienced who want to kick back and just enjoy what a wonderful product these are. So far I've just slipped in the 4.8 in plug (second to largest) to enjoy while I'm writing this review and anticipating how awesome the 1.6"×6" is gonna feel, at the moment I'm simply at the melting point, I can only imagine what me big is gonna do too me later. Super professional packaging, very discreet and comes in a really nice box, honestly you gotta go there, I thoroughly pleased and very impressed, thank you Amazon, I'm coming back for more, for Christmas presents that is, LOL!This kit has everything you need if you want to start exploring anal play. Comes with 4 different size plugs, a small tube of lube and an anal douche. Searching for any of those items individually, you will see them listed for about the same price as this entire kit.One note: I purchased this kit because any attempts at penetration from my husband were excruciatingly painful. That being said I expected to have to start extremely small. However the two smallest sizes were very easy to insert and caused absolutely no pain. If this is something you already do regularly and are used to these plugs may be too small for your enjoyment.
