I am really excited about bringing this product to everyone’s attention. I think I have found the Holy Grail of e-stim electrodes, the stunning looking Large Flo electrode from E-Stim Systems.

Anyone who knows me and reads my reviews knows that I am a bit of an electro queen, and I have a vast collection of electrodes that I regularly use. My collection includes electrodes from lots of different manufacturers, including some that I have made myself.

There is something very comforting and relaxing when you lay your eyes on a professionally made electrode though, especially one as good looking as this one.

E-Stim Systems have a range of electrodes called the Red Collections, and I was lucky enough to have been able to review the Bobble many moons ago. At the time, I really liked the design of the Flow, and so I recently bought myself one to review, and I am so glad that I did.

If you want to read a quick primer of electrostimulation (e-stim) you can read my guide here – What is E-Stim or Electrostimulation?

So, let me tell you why that is and why I highly rate this particular e-stim electrode.

Delivery and Packaging

Latex, Leather and Lace always provide lightning-quick delivery, and you can rely on their packaging being very discreet.

My postman still has no idea what a kinky lass I am. As long as I keep ordering from safe sites like Latex, Leather and Lace that won’t ever be a problem.

All E-Stim System electrodes come in lovely screw-top machine tool holders, and these are perfect for the job of holding these electrodes.

These tool cases are perfect for electrode storage

This one though is unlike the usual black ones you get from E-Stim Systems. It is a striking translucent red and matched the theme of the Red Collection perfectly. Even the box looks sexy as hell.

Inside you will find some padding, instructions for the care of your electrode and of course the Large Flo itself. It’s hygienically sealed in shrink plastic, this means you know it hasn’t been tampered with on its journey from the factory to you.

I was blown away with the finish on this electrode

Materials and Design

I actually gasped when I took the Large Flo out of its packaging as it is beautiful. I was mesmerised by my reflection in the polished aluminium.

My mother always said that you eat with your eyes first. So if its stunning looks were anything to go by, then my pussy was in for a treat. The aircraft-grade aluminium that it’s made from is polished to a mirror finish, and it looks incredible.

I have no idea how E-Stim Systems get it so shiny, but the finish is flawless, and as you can see from these pictures, it has a mirror-like finish.

The Large Flow Electrode looks amazing with its mirror finish

Having used mine numerous times now, I can also confirm that it is still as shiny as when I took it out of the box for the first time.

The hourglass shape of the Flo electrode is very becoming, and the red insulating band in the middle gives it a classy and stylish look. This is a bipolar e-stim electrode that really emphasises what excellent craftsmanship looks like.

Between uses, you can use a 6mm Allen Key to trip it down for a deep clean. The ridges around the base make it very easy to hold on to when inserting or retrieving it at the end of a play session.

The base of the electrode has two 4mm sockets in it. One for each electrode surface and so you will need a cable with 4mm banana plugs on the end.

The sockets in the base are logically placed and the ridge around the edge makes it easy to hold

I recommend getting the low profile cable made by E-Stim Systems as the Flo doesn’t come with a cable. It makes seated play much more comfortable and relaxed.

The centre socket leads to the electrode on the end of the Flo, and the outer one is for the base segment. This is a bipolar electrode, but of course, you could just connect one cable and use it as a monopole electrode too.


The Flo comes in two sizes, the large one that I have and also a small one, this one measures in at:

  • Length 120mm
  • Insertable Length 110mm
  • Head Diameter 37.5mm
  • Base Diameter 50mm
  • Weight 268g

The Large Flo feels substantial in your hand, and this is something very noticeable when you insert it.

The nicely rounded head makes vaginal insertion easy. If you intend to play with it anally, then you will need to take your time. Building up pressure until your sphincter dilates to take it inside you.

The rounded tip is a lot of fun to insert

This electrode is far too big for me to enjoy anally, but I know anyone who does so is in for a real treat. I may have to get the smaller one to enjoy some backdoor e-stim fun.

Like all E-Stim Systems electrodes and control boxes, you get a lifetime guarantee with it. They are so confident of their quality control that they can offer this incredible guarantee. They make all of their electrodes in house here in the UK, and that gives them total control over every aspect of their products.

Ease Of Insertion

The Large Flo Bipolar Electrode is a fantastic electrode. I have had no problem edging myself to some incredible orgasms with it.

As with all insertable electrodes, you should use a good quality water-based lube such as E-Stim Systems Electrogel.

Never use anything oil or silicone-based as they are insulators. The lube is there to ensure good electrical contact as well as aiding its insertion.

The large head of the Flo feels incredible as I push it into my vagina. Because it isn’t really tapered you feel the pressure building as you push it inside until your vagina opens up to take it. Once the head is in, it almost draws itself into you due to its hourglass shape, and that feels amazing.

The base sits nicely between my labia and just inside the entrance to my vagina.

The Large Floe is very well proportioned and filling


I prefer an end to end electrode configuration rather than the side to side ones, and the Flo is perfect for me. The hourglass shape was designed primarily for vaginal play, but it is equally suitable for anal play too.

As the electrical current flows, the hourglass shape heightens the ghost fucking sensation, which is impressive. As your muscles clench, it causes the electrode to move inside you. That gives the impression that you are being fucked. In conjunction with the delicious e-stim sensations it is a surefire winner in my books.

Lower power levels feel delightful, and as you turn up the dial on your control box, the action gets hotter. Once the ghost fucking sensation kicks in, I am in heaven, and it drives me wild.

This is an electrode that will both fill and delight anyone using it. The mirror finish means this could be classed as an electro-selfie

I regularly get this effect with other end to end electrodes. But never to the extent, I can enjoy with the Large Flo. This is the reason why it is now my goto electrode when I want some kinky ghost fucking action.

The size of the Large Flo makes it a nice and filling electrode. It gives you something hard to clamp down on as you orgasm. I relish the sensations of how cold it is when I first insert it. I am always amazed by how warm it is when I pull it back out again after a good session.

Cumming hard with it inside me is delightful, and I have to close my legs to prevent me squeezing it out as I orgasm. It is never a good idea to allow it to be squeezed out when the control box is on. Your pussy lips will get a zap as it leaves you.

The Large Flo feels terrific on all of my control boxes, but the 2B gives it the most power, especially when using the mains power adaptor. If you have a low powered TENS unit, then the Small Flo may be a better option due to its smaller surface area.

All in all, the Large Flo is a fantastic bipolar electrode to enjoy some nice ghost fucking. It is equally at home in a pussy or a tight ass. The hourglass shape assists in it moving as your muscles clamp down upon it, giving you a nice ghost fucking.

As usual, Latex, Leather and Lace can be relied upon where the whole ordering experience is concerned. The lifetime guarantee is excellent too as it gives you total peace of mind.

In the unlikely event that something goes wrong with this bulletproof electrode, E-Stim Systems will be there to help you out.

I love the Large Flo and may have to get myself one of the Small Flo electrodes from some anal fun and games.

This electrode has the performance to match its incredible looks. So if you want to try a fantastic bipolar insertable electrode, then the Flo needs to be on your shopping list.
