CRP Keycaps Review

CRP keycaps Review can be completely done on different technical benchmarks tests like their sound, durability, compatibility, feel and cost.

Let’s see how these keycaps perform in all given benchmarks.

Here are the all technical factors:

1. Sound

As far as the sound profile of CRP keycaps is concerned, they have a much deeper sound due to having a PBT profile.

Do you know?

PBT’s are known to generate a deep sound profile because of the thick and high-quality plastic material from which they are made.

Dye-subbed legends make a significant difference between a regular PBT and Hammerworks CRP keycaps sound, you may feel CRP’s have a little crispier and clear sound while typing.

This crispy sound is pleasing to our ears and is mostly loved by the user.

Overall, the Sound profile totally depends on the individuals as some like loud and clacky sounds whereas some like quieter sound profiles.

So which kind of user you are, you have to know before buying.

2. Texture and Feel

In terms of texture, CRP keycaps have a rough-textured on top of it due to their thick and premium material while making. 

CRP’s inherited most of the character from conventional PBT’s however some unique properties they equipped their own.

Equipping the property of rough nature and a textured feel, these keycaps allow excellent hold over the keyboard during typing, unlike ABS keycaps which have shinier touch.

If I talk about in-hand feel, these keycaps feel great in the hand so you feel much better with a good hold while typing on these keysets.

In terms of look, CRP keycaps have a stunning color combination which not only enhances their appearance but also resist color to fade in sunlight.

Overall, I like their design and feel.

These combinations of color definitely make your office and space look better with perfect keysets.

3. Melting Point

When a substance changes its state at a certain temperature, this temperature can be referred to as a Melting Point.

So a keycap having a low melting point simply means it’s easy to mold whereas a keycap with a high melting point means it is difficult to mold.

ePBT’s molding was not that good initially, so CRP beats them with their straight molding and dye-sub keycaps legend.

If you look at all specialties which make them sturdier, you will surely conclude that CRP keycaps are the best PBT on the market.

ABS keycaps melting point is 105-degree which is low and it usually takes less energy to be molded that’s why they are less expensive. 

Whereas PBT keycaps Melting point is 225-degree which is high that’s why they take more energy for molding and come at a slightly higher price.

Sometimes key warping problems can be occurred in PBT’s due to their very long cooling period time.

4. Compatibility

Compatibility is the most significant factor for a user to consider these CRP Keycaps.

As these keycaps are inherited from the Cherry MX keycap profile, so if you are the kind of user who is used to cherry keycap profile then you will require very little time to get used to it.

These keycaps are sculpted in a manner so that they can acquire the shape and structure like cherry keycaps.

CRP’s are compatible with most of the standard key layouts so you should not be concerned about their compatibility.

They work smoothly with almost all mechanical keyboards.

5. Cost

Price is an important factor that makes you decide, consider it or not for your mechanical keyboard.

These switches can be looking costly to you at first glance because of the PBT profile but believe me, CRP keycaps are quite economical compared to some other keycaps which are too expensive.

Considering their specification and the value they are providing to you in this budget, I think it’s one of the best PBT keycaps out there on the market.

So if you looking for a keycap that can fulfill all your requirements within a budget-friendly option, you can go with CRP keycaps without a single doubt.

I will definitely recommend it for your mechanical keyboard.
