Customer video review of Wandjamin Cart Battery with LED Light & Slide to Hide Feature

Kari P.Verified

I love the wand!! Super cute. The slide to hide the cart is an awesome feature. Making up spells and popping up the cart is just pure amusement. I have several pens, but the wand is quickly becoming my favorite. Too bad I can't smoke at the cancer clinic. I'd bring it to my Halloween treatment dressed as a witch.

Such a fun pen battery. My friends and I have not gotten tired of it yet. We chuckle every time we use it. Last weekend we were placed in room #420, and after the concert the Hobbit was playing. It was meant to be. ❤️ #tipperredrocks

Penjamin by Smyle Labs is the BEST cart battery I've ever owned!!! My last pens I had for over 2 years and only needed to replace them because I had worn the paint off and lost pieces but the batteries still too charge and worked perfectly!!! I've had black and glow in the dark so super excited over the purple one!!!!

Amazing, will be buying more. I highly recommend the penjamin as it is amazing quality. I only wish it had USB-C instead of Micro USB yikes. Either way this thing is amazing and works just as expected. HIGHly recommended!

I bought this when my 1y/o Pulsar bar stopped putting out quality hits. I get a MUCH bigger hit and the battery life on this is great! Takes a USB-C charger (in case you were wondering) I yell Leviosa when I hit cuz it gets me elevated 🤣

Customer video review of Inhaler 510 Cart Battery + Cloud Filters

Tanya B.Verified

This little thing is so cute. It's nice and discreet. It has two sizes to use for different size carts. Also comes with two filters. It's very nonchalant. I love it.

Smyle Labs this is the BEST 510 battery I have ever purchased. Thank you soo much. So discrete, and so easy to use. You cant even tell which inhaler is the real one unless you look real close. No one will ever notice!

Liz G.Verified

This thing is hilarious. It is comically big (I thought it'd be closer to a regular-sized pen), but I got the black one so it still looks pretty inconspicuous. It appears to be really sturdy and well-made. It works great and I prefer it over my other regular battery now!

This is my new favorite pen!! She is so cute and I feel like a real sailor scout everytime I use it. Please my order shipped and arrived really quick!

Salina C.Verified

Its like double the size of a normal writting pen. Glows super well! And funny enough i couldn't find a pen for a quick note, i remebered i had that in a safe location and BAM! Note taken! Because of what it is, i know i wont lose it, so ill ALWAYS know where atleast 1 writting tool is in my home. This thing is awesome.

Phillip H.Verified

This thing has surpassed expectations! Excellent warm up feature, smooth hits. What a wonderful product. Worth every penny, wish I had gotten that second that was offered. Didn't know it was going to be so awesome.

Robert M.Verified

It's hard to choose which Smyle Labs 510 battery is my favorite. And they are all very discrete! The buttons all click on this remote, even the buttons you don't actually use. And there is a USB C charging port on this device!

Kyra C.Verified

The pen is great, love the modes, and the led colors, and the functionality as a whole is perfect, AND it glows in the dark! Everytime I hold I can't help but giggle with childlike joy

Katrina H.Verified

It would be cool if the pen were thinner, and I thought it was green. Not only green when it glows in the dark, which is still cool and it works perfectly and is definitely discreet.

I love it i was very skeptical of it because I bought the car.Key and I did not like it, but I love this very, very nice.One hundred percent recommend

Natalie H.Verified

Does its job. Hides Cartridge. Rubber with hole for easy access. Button you can also hide with the cap. Charges really fast, color turns off when done charging. Look just like a normal pen😉 And it’s cute 10/10!

Jordan D.Verified

Incredible! The exact creativity I’m looking for in a piece! It’s functional, discreet, no one questions an inhaler! I’m obsessed! Well worth it and will be purchasing for friends. Looks legit and fun for novelty!

Love the battery, it has a solid battery life and rips pretty smooth as well, I personally keep the cap off since I’m always moving at work which makes it pop off

Michael E.Verified

I love this battery. I do have a couple of problems like the brown wand is just the black wand with paint smeared and not sealed (comes off very easy. Should have a 3rd locking spot. Now the battery is wonderful I leave it in all day and I charge every 2 days that’s with heavy use. 4 clicks should show battery life. That is my honest option and I do love this wand

Rebecca H.Verified

This is adorable and lightweight. I love it! It doesn't shut itself off automatically, so just make sure to power it off before putting it in your purse. The pic is next to a 40oz tumbler for size reference.

I found this from a friend on twitch and she told me the brand and immediately wanted the red lightsaber one..wasted no time in ordering it. I love this and the magnet inside that keeps the cart secure. My new favorite battery

Customer photo review of Inhaler 510 Cart Battery + Cloud Filters

Geoff S.Verified

This is by far one of the best devices I’ve found—discreet, easy to use, and incredibly convenient. I actually brought it with me to a Spring Training game recently and was a little worried when we got to security and they had everyone empty their pockets before walking through the metal detector. I honestly thought that might be the last time I’d see it. To my surprise, the security guard looked at it, smiled, and said, “I have asthma too—I keep mine with me all the time.” I winked and said, ...

A real asthmatic would notice it looks funny, but someone who doesn’t regularly use/have an inhaler would hardly be able to tell a difference. It’s discrete and easy to use!

Customer video review of Lip Balm Cart Pen By Smyle™ Labs

Aaliyah Y.Verified

Love this!! Battery works great, it hits smooth and they're super discreet and super cute, totally recommend if you're just looking for a battery or need a discreet one. The only things I feel I should include are the fact I had to add the keychain peice to the container that holds them, the pink is actually more purple, and the cart may rattle in the storage container, unless you leave the rubber pieces on your cart that are on it when you first unbox it. It also came with 2 charger covers, but...

Keith R.Verified

The inhaler is remarkably easy to use, with four power settings to choose from. I like that it's draw-activated, so it doesn't use a lot of power. I charged it when it arrived four days ago and haven't needed to recharge it despite moderate use. The cloud filter does a great job of making the cloud disappear without a trace. It has a preheat function, but the carts I'm using aren't thick, so I haven't needed to road-test that function yet. Overall, I would recommend this for discretion and esse ...

This thing is awesome I love it my friends love it I bring it around there like no way I need one of these so I'm promoting you guys too you know I'm telling them where to get it I've already got a lightsaber got that last Father's Day this just adds to the collection and it's freaking awesome.

Michele S.Verified

I like it! Was hoping to get something that works well and is more subtle if I leave it sitting out by accident and it's a success. Only complaint it that the tip of my cartridge is white and you can see it around the rubber "pen cap"

Cart Pen by Smyle™ Labs

Erika C.Verified

The Smyle™ Labs Cart Pen is such a clever little device. At first glance, it looks like an ordinary pen, but it’s actually a discreet pen battery that functions as a real writing pen too. The design is sleek and feels durable, clearly made from high-quality materials. What I love most is the combination of functionality and subtlety—it doesn’t draw attention, and the dual purpose makes it super convenient to carry around. Smyle™ really nailed the balance between style, practicality, and performa...

Seth M.Verified

Needed a new battery so I got this as my daily replacement, super discreet no one knows what it really is until you tell them or they really look at it close up. Overall 9/10 only flaw I have with it the battery life could be just a little bit longer lasting have to charge it at least once a day.
