We’re Back! It’s a brand new year and I’m starting with a quick apology. 2023 was not the best year for me, and things went a little downhill towards the end of the year but we’re attempting to bounce back and so here we are; out first review of 2024 (and it’s an overdue one!)

The life of a sex toy reviewer is rarely smooth sailing. I’m not going to sit here and give you a full deep analysis on why we went quiet towards the end of the year. The important thing is that I am here now and I will be for the foreseeable future and I already have a stack of reviews lined up. So I thank you for your patience and let’s kick things off! Towards the end of 2023; the lovely folks over at Kiiroo very kindly sent me some additional sleeves that they were working on, for use with both the KEON and the POWER BLOW; 2 products that have been incredibly popular (and if you’ve tried them – it’s not difficult to see why).

The two sleeves that were sent to me was the Extra Tight Butt sleeve; and the FeelGlow sleeve (yes, as the name suggests, it glows in the dark! More on that later). Of course, life got in the way and I’ve only been able to turn my attention to them recently. So without further ado, let’s quickly dive in and see what we thought of these new offerings.

I would like to thank Kiiroo for sending us the Extra Tight Butt & FeelGlow sleeves free of charge in exchange for an honest review. Affiliate links have been used in this post. 

First Impressions

When it comes to these sorts of products, you pretty much know what you are going to get. The standard KIIROO packaging with your sleeves inside. You’ve seen one, you’ve seen them all. Going forward, I will be referring to the Extra Tight Butt as the ETB for brevity. The ETB is your standard black case with a butt orifice and a tightly coiled internal texture. The Glow is in a translucent case, and the sleeve is made with a translucent material. It features a fairly standard vulva orifice and has a tightly-packed ribbed texture on the inside. If you place the Glow under a bright light for a while, when you turn the lights off – you will be treated to a lovely little light show.

Both sleeves have been designed for use with the KEON and the POWER BLOW; and for the next section of the review, we’ll be looking at each sleeve separately and break it down into solo use; with the KEON and with the POWER BLOW.

In Use

Extra Tight Butt

Solo Use

As with any masturbator, the first thing I like to do is test the sleeve out on its own, without any of the bells and whistles; just to see what it can do. This is the second butt sleeve we have tried from KIIROO and can indeed confirm it does live up to its name. With the standard butt sleeve; I lamented how it felt ‘OK’ – I was longing for a bit more tightness and more texture. Well they delivered. The ETB feels realistically tight and snug; and it really grips every inch of my shaft. The twisting texture has been increased, and it’s not as noticeable when just manually stroking but… well, I’ll get to that shortly.

All in all, so far, the ETB is definitely an improvement over the original Butt sleeve; so those of you who crave something a little more intense – this might be the sleeve for you. Let’s whack it into the KEON and see how we feel.

Keon Use

Installation of the sleeve into the KEON is simple and once I’d found the right entertainment for it – it was a mind-blowing experience. The texture is what really wins here; combined with the added tightness – I could close my eyes and I was lost in the moment. I would go so far as saying this has been my favourite sleeve to use with the KEON. It will definitely see regular play for sure.

Power Blow Use

Given how well this worked with the KEON, I was already under the illusion that it was also going to work amazingly with the POWER BLOW and well, yeah… it really did! For those who like their suction very deep and intense… this is definitely the combo to go for. I didn’t even need to stroke with it at all. Just allowing the PB to just squeeze my cock yielded an absolutely knee-trembling orgasm that left me breathless and panting. This is definitely a winning sleeve in my book.

Glow Sleeve

Solo Use

The Glow sleeve; I’ll admit I wasn’t expecting it to have a vulva orifice – but I’m not one to let that stop me. Before using it, I left it under a bright light to ‘charge’. After a couple of hours, I was ready to give it a try and so took myself away to a darkened bedroom. As soon as the lights were off; the sleeve emitted an eerily beautiful blue glow. So it certainly lives up to that part but what does it feel like as a stroking sleeve? In short – OK. It’s not as tight as the ETB but the texture is pleasant enough. The see-through aspect is always a turn on – I love being able to see the cock inside the sleeve (whether it’s mine or someone else’s). The Glow was a nice touch and whilst it didn’t really add anything just for me in the bedroom; I can imagine anyone who does any cam work; this could certainly help create some memorable content.

Keon Use

When used with the Keon; yeah it does what it’s supposed to. It’s not that it feels bad, the sensation just doesn’t quite excite me in the same way that the ETB did. I think I just really prefer tighter sensations. But it still felt pleasant – It’s just not necessarily a sleeve I’ll return to that often.

Power Blow Use

However, stick the sleeve in the POWER BLOW and the experience is much nice. I think because you can make the sleeve tighter; it allows me to really explore and feel every nuance of the texture. I will say the added enhancement of the see-through sleeve and glow aspect certainly made for a more visually appealing spectacle as well.

Clean-up and Maintenance

As with all sleeves like this, clean-up is simple if slightly time consuming; especially with the ETB. You’ll really need to pay attention to ensure everything is removed from every little nook and cranny in that tight, twisting texture. A good rinse with warm, soapy water is enough to give these a clean but pay attention; as these are made from a TPE/TPR type material – these need to be thoroughly dry before being stored away as mould can potentially grow if not taken care of properly.

Once they are fully dry, a light dusting of renewal power or cornstarch will help keep the sleeves feeling smooth and silky – then pop the sleeves back in the cases and you are ready for your next session.


Who knew I could write so much about some basic sleeves? The KEON and the POWER BLOW were certainly massive surprises when we reviewed them, and it’s great to see KIIROO continuing to grow the range and add new sleeves. The ETB for me, is certainly a welcome addition to the range and I hope in the future we start to see some feel stars from gay porn making their way into the roster. I think that’s the only thing that’s really lacking from their range – whether it’s butts or mouths. Equal opportunities and all that!

As for the Glow; sure it’s a fun concept and it feels OK – is it necessary? Not really – I already have plenty of see through sleeves in my collection that feel great. But I maintain if you are someone who produces regular spicy content OR you do cam shows – I think it would certainly make your next show a memorable one. But for me in the privacy of my own bedroom? It doesn’t really add anything to the experience.
