YiHi SX Mini Mi Class Pod Kit Review – Is It Style Over Substance?

The SX Mini Mi Class is the first pod kit from the company that made the iconic and vape reviewer favourite the G Class and of course the timeless workhorse the Q Class, which this old timer bought – loves and still uses today.

The release is I’m guessing the semi-high end vape company’s answer or should I say attempt to match the incredible reception and sales the Lost Vape Orion pod kits have made – as to if SX Mini has achieved this we shall see.

OK the Mi Class has an internal 400mAH battery and is powered by the YiHi SX290 chip and powers up to 13w.

At the time of writing there’s only one coil option for the 1.5ml pods – a 1.ohm ceramic and I don’t know if SX Mini is planning on releasing any new ones.

This was sent to me free of charge for the purpose of review – thank you – and as always my thoughts and opinions are my own.

In the Box

As you might expect from a class company it’s a classy box and inside you’ll find:

• 1 SX Mini Mi Class Device
• 1 MicroUSB Cable
• 1 Instructional Manual
• 1 Warranty Card

Note: If buying from the UK and EU for some reason one pod should be sent and boxed separately – mine came from China and the pod was already inserted. In my case the instruction manual was only in Chinese lol…Pfft who needs instruction manuals…so double check what you’re getting before buying 😉

Key Features

There appears to be an EU version of the Mi Class out there – I’ll explain the difference later. So you’ll have to bear with me as I use the features described on the VapeSourcing site – from where mine was sent from rather than the manual. Hope that makes sense because my Mandarin sucks…

I can definitely tell you the pod kit is powered by Yihi’s latest SX290 chip and in this case has a power range of 7 to 13w and has a 400mAH internal battery.

Now according to UK and EU websites selling this, the pod should come in a separate box – mine came already attached inside the main box…so please double check when buying – especially from China – to make doubly sure a pod is included! I’m also a little confused about capacity…some sites say 1.8ml whilst others say 1.5ml…not much of a difference in the scheme of things I suppose…

Jeez this is already confusing the hell out of me lol.

The Yihi SX Mini Mi Class has a screen, which is unusual for a pod kit, and you can adjust the brightness with 5 clicks. The screen also has a battery level indicator and shows current voltage but not the wattage and a puff counter. Incidentally the puff counter resets every time you recharge the device…bit weird…

The 1.5ml [EU] pods have a ceramic coil with a resistance of 1.0hm so this is definitely a Mouth to Lung (MTL) device and there’s no airflow control.

The key difference between the one I received and others I’ve seen on sale and in reviews is the fill system. On the EU versions filling was a fiddly process. You have to unscrew the mouthpiece and then peel off a silicone bung. From watching earlier reviews filling looked like a right pain in the proverbial to say the least.

However, on mine you unscrew the drip tip to reveal two tiny kidney shaped fill ports. Why there’s a difference between the rest of the world and the EU I’m not sure…

OK I’m getting into performance here…and my brain hurts lol…so let’s move on.

Design and Build Quality

Design wise it’s very pleasing to the eye – though saying that I’m not a fan at all of the paisley tang ‘photochemical etching‘ – all a bit grandma’s curtains for me – I really didn’t like it on the G-Class either…*ducks* lol.

However on the black and silver it isn’t in your face and looks OK and also acts as a nice grip when in the hand.

Apart from that flowery stuff I quite like the design – it’s sleek – the adjustable screen is very clear however the fire button is not at all clicky – the word spongy comes to mind if that makes sense.

The tiny SX Mini logo is stamped onto the side and even that looks good – it’s the little details that make classier devices stand out for me. There’s really no need for a mod or tank to have HUGE logos slapped everywhere.

Saying that there does appear to be a long serial number etched on the side which whilst hardly visible is a little strange design wise…

The design of the pods especially the filling method is much better in the rest of the world editions. Mine has the two fill ports – though they are tiny and 10ml bottle nozzles just about fit with no spillage. There’s also a drip tip cap that comes on and off which I’ve lost a few times already lol…

To pop in the pod you need to line up the groove with the runner and push down. One design/build issue I don’t like is there’s no snap or click when the pod is housed correctly – it just kind of sits there. Though to be fair I’ve had no connection issue with the device in my pocket and when out and about…I do miss that satisfying click though lol.

OK and as you might expect from a classy company the SX Mini Mi Class kit is well built. The main body is made from stainless steel and still manages both a feeling of toughness whilst remaining light in the hand. The pod is obviously plastic whilst the drip tip is Delrin – and sadly this is proprietary so no chance of using other 510s.

How Does the Yihi SX Mini MI Class Perform?

You’ve had a big build up to this point so let’s hope it’s worth it…

There’s no airflow or power control so what you get is what the battery is pumping out and how much air the pod sucks in – I can say this is definitely a proper MTL vape. Not sucking your cheeks in until your eyes pop tight but close enough.

I used Black Note Legato 3mg to test this out – after all a posh pod deserves a quality juice.

Flavour – Vapour and Throat Hit

Sadly the flavour off that ceramic coil is muted to say the least and that’s me being kind.

Why oh why go down the ceramic route when the world and his uncle knows mesh is the way forward…mostly. Vapour production – if that’s what you’re interested in – is pretty good…but most of us prefer flavour to clouds especially off a pod/MTL device.

I didn’t get much if any throat hit either – I got a little tickle swapping the normally robust and flavoursome Legato for a 12mg strong tobacco blend but nowhere near the best I’ve had by a country mile.

I tried it with a sharp and tangy 20mg nic salts juice and whilst the residue of two other e-liquids did make for a weird taste – I have to say the flavour off the citrusy fruit juice was still poor – even after another half fill.

I would like to have tried more flavours in fresh pods but didn’t have any. However if the strong flavour of the Legato didn’t come through in the first and second fill I really have no choice but to say the flavour is disappointing to say the least…

Pros

• Good chip
• Well built
• Nice design
• Easy to operate
• Easy fill
• Decent vapour
• Good battery life
• Screen…

Cons

• Muted flavour
• Poor throat hit
• No power control
• No airflow control
• Ceramic coil – dated?
• Lack of other coil resistance options
• Pricey

Final Review Verdict

If SX Mini’s nearest semi high end rivals Lost Vape nailed it with the Orion Q and DNA Go version then sadly SX Mini has hit their thumb with the hammer.

Sure it looks lovely and the alternative fill system on mine is much better. But looks aren’t everything especially in vaping as this one proves IMHO.

The vape is weak – the flavour muted and watery – there’s no airflow control or even the simplest power select option and the only redeeming feature I guess is vapour production, which certainly isn’t something I consider when reviewing or buying MTL devices.

I think if they brought out new pods with a mesh or even cotton coil things might perk up a little – but for now it’s all a bit meh and definitely a case of style over substance…that’s me off their Christmas card list lol…

The best way I can describe this is it’s like having a stunningly beautiful yet vacuous model on your arm – looks good as a trophy wife/girlfriend but there ain’t nothing between those ears…

So sadly, the Yihi SX Mini Mi Class is not one I recommend…unless of course you want a stylish trophy vape in your hand 😉
