15 reviews for Requiem RBA Designed By ELMONO VAPEADOR In Spain
Debo decir que es una RTA con una construcción muy bien pensada, podrás personalizar el tipo de calada como más te sea satisfactoria. La verdad que la calidad de construcción es sobresaliente, un RTA para boros que se podría catalogar dentro de los mejores high end de RTA para boros que ahi en el mercado. No soy de usar mucho los boros, pero desde que tengo este RTA no he dejado de usarlo, así que lo recomiendo al 100 % si quieres un buen RTA para boros no te lo pienses mucho, no vaya a ser que te quedes sin el tuyo

One of the best Rba’s
I love the Requiem Rba! It’s different from any other Rba out there, easy to set up, has lots of airflow options, creates amazing flavor & huge cloud production too. Another winner by Thunder Cloud and a definite must have!! I’ve ordered several great products by Thunder Cloud, for myself and for my coil customers too. They have amazing customer service and fast hassle free shipping, not to mention great products at great prices! I’m definitely a customer for life! Thank you Thunder Cloud!

Amazing taste, convenience, and variety
What I like about ThunderCloud’s atomizers is that they’re release well-designed devices that combine years of experience and have a solid implementation. Additionally, it’s clear that the company’s products are aimed at the European market, as they offer good quality and a professional appearance. If I hadn’t been told that they were made in China, I would have assumed they were from a European company. The atomizer itself is gorgeous, versatile, and delicious, which is why it recently won an award at a European exhibition.

High-quality Boro tank with plenty of airflow options
This Boro tank allows you to freely combine side and bottom airflow.
The overall construction is excellent, and it has almost all of the inconveniences I’ve had with previous Boro tanks, making it very easy to use.

🛠 Requiem RBA – The Boro Baptism That Didn’t Break Me
Reviewed by The Old Goat
Let’s get one thing out of the way upfront: I’ve reviewed a lot of gear. RTAs, RDAs, mechs, pods — you name it. But the Requiem RBA? That was my first proper dip into the world of Boro-style AIOs. And let me tell you — it set the bar higher than I expected.
This little Spanish-engineered masterpiece, a collaboration between ThunderCloud and ELMONO VAPEADOR, doesn’t just look premium — it performs like it knows it’s already won “Best Atomizer of 2025.” And frankly? That award feels well-earned.
Build Quality & Design
The machining is top-tier. Every part fits together with the kind of tight tolerance you’d expect from a high-end mod — not an internal RBA. It’s compact without being fiddly, robust without being bulky. The deck layout is intuitive for a single coil setup, and the airflow design (both side and bottom options) makes it versatile for a wide range of vape styles.
The fact that it comes with multiple airflow pins — including both bottom and side options — means you’re not locked into one feel. You can go tight MTL or airy RDL, all without hacking your way through aftermarket accessories. The dual refill system (front and side) is clever and makes real-world use that much easier.
Performance
Once built and wicked properly, the Requiem delivers exceptional flavour. I mean that. I’ve used plenty of rebuildables over the years, and this one punches well above its size. The airflow is smooth and quiet, and the deck provides enough space to comfortably install a fused Clapton without swearing at your tweezers.
No leaks. No dry hits. No fuss. Just consistent, clean, saturated flavour. Exactly what you want in an RBA.
Who’s It For?
Honestly? It’s great for experienced builders, but surprisingly friendly for Boro newcomers like myself. If you’re coming from standard RTAs or RDAs and want to test the AIO waters, this is a fantastic place to start.
It’s a precision instrument, but not a diva. It gives you what you put into it — and if you know your way around a coil and some cotton, it’ll reward you tenfold.
Final Thoughts
The Requiem RBA made one hell of a first impression. Not just as my first Boro device, but as a benchmark for what a modern RBA should be: well-built, flexible, flavour-focused, and thoughtfully designed.
There’s always a risk when you start with the best — everything after might feel like a step down. But that’s a problem I’ll happily live with if it means more gear like this gets made.
Bravo to ThunderCloud and ELMONO. You didn’t just raise the bar. You made something worth chasing.

Incredibly surprised RBA boro requiem
The Requiem Boro RBA stands out for its compact design and its multiple air configuration. I can play from MTL to DL RDL. It’s very fun, but it’s also worth highlighting the flavor and hit are excellent. I love it and use it very often to achieve nuances in my e-liquids.
