My Buying Guides on Mg 1/100 Ex-s Gundam/s Gundam

My First Impression

When I first looked at the MG 1/100 Ex-S Gundam / S Gundam, I immediately saw that this is not a casual purchase. It is a large, complex, and highly detailed Master Grade kit that feels aimed at experienced builders or collectors who want a serious centerpiece. In my opinion, the design alone makes it one of the most impressive Gundam kits in the MG lineup.

What I Consider Before Buying

Before I buy this kit, I always think about a few important things:

  • My experience level with Gundam model kits
  • The amount of display space I have
  • Whether I want the Ex-S Gundam, the S Gundam, or both configurations
  • My budget, since this is usually a premium kit
  • How much time I am willing to spend on assembly and detailing

For me, this is not the kind of model I rush into. I like to make sure I am ready for the build and the size of the finished product.

Build Complexity

I would say this kit is best for builders who already have some MG experience. The Ex-S Gundam / S Gundam is known for being intricate, with a lot of parts and a demanding assembly process. I personally see that as part of its appeal, but I also know it can be frustrating if someone expects a quick build.

If I were recommending it, I would say:

  • Good for intermediate to advanced builders
  • Not ideal as a first Master Grade kit
  • Requires patience and careful part handling
  • Rewards attention to detail

Size and Display Space

One thing I always keep in mind is how much room I need for display. The Ex-S Gundam in particular is large and visually dominant. My display shelf has to be prepared for a kit of this scale.

I also think about poseability. Because of its size and heavy equipment, I would not expect extreme action poses. I look at it more as a display model than a dynamic action figure.

Ex-S Gundam vs S Gundam

When I consider this kit, I like to think about which version I want to emphasize.

  • Ex-S Gundam: I prefer this if I want the more massive, upgraded, heavily armed look.
  • S Gundam: I choose this if I want a slightly cleaner and more balanced appearance.

In my opinion, both versions are attractive, but the Ex-S form is usually the one that makes the biggest visual impact.

What I Look for in Quality

I usually check the following before buying:

  • Mold quality and part separation
  • Color accuracy out of the box
  • Stability of the joints
  • How well the weapons and armor fit together
  • Whether decals or markings are included

For me, a good MG kit should look impressive even before painting, and this one generally delivers that kind of presence.

Tools and Preparation I Recommend

If I am building this kit, I make sure I have the right tools ready:

  • Nippers
  • Hobby knife
  • Sanding sticks or files
  • Tweezers for decals
  • Panel lining tools
  • A stand or support if needed

I also like to work slowly and organize the runners carefully. With a kit like this, preparation makes a big difference in my experience.

Who I Think Should Buy It

I would recommend the MG 1/100 Ex-S Gundam / S Gundam to:

  • Gundam collectors who want a premium centerpiece
  • Experienced model builders
  • Fans of the Sentinel design
  • Builders who enjoy complex and detailed kits

I would not recommend it as a beginner’s first choice unless the person is very patient and willing to learn as they go.

My Final Buying Advice

If I want a kit that feels impressive, challenging, and highly display-worthy, the MG 1/100 Ex-S Gundam / S Gundam is absolutely worth considering. I see it as a premium purchase that offers a lot of reward for the effort invested.

My advice is simple: buy it if I want a serious project and a standout model, but make sure I have the space, tools, and patience to enjoy it fully.

Final Thoughts

I think the Mg 1/100 Ex-s Gundam/S Gundam stands out as one of the most impressive and rewarding Master Grade kits for builders who enjoy detail and complexity. My takeaway is that it offers a strong mix of striking design, excellent shelf presence, and a satisfying build experience, even if it demands patience and care. If you appreciate large-scale Gundam models with a lot of mechanical depth, this kit is definitely worth considering.
