The Specs: On Paper

On paper, it's a straightforward comparison. The Moza R21 has more torque (21Nm) compared to the Moza R12 (12Nm), making it the clear winner in terms of raw power. The R21 also comes with the same Direct Drive type and compatibility with PC as the R12.

The Ugly Truth (Real User Experience)

I've seen some users experience issues with the R12, such as FFB dropping to under 50% strength after extended periods of use. It's not just me; multiple users have reported this problem, and I'm starting to think it's a design flaw rather than user error. The company has been inconsistent in replacing faulty units, leaving customers frustrated and disappointed. One user even had to deal with two separate bases that exhibited the same issue, only to be told by customer service that there was no issue at all. Dealing with overheating issues is a nightmare – I've heard from several users who've experienced it firsthand. Not only does it affect performance, but it also adds stress and anxiety to an otherwise enjoyable experience. I've lost count of how many times I've seen users lament about the Moza R12's reliability issues. The R21 seems to fare no better in terms of customer satisfaction. While it doesn't have as many complaints regarding overheating or FFB drops, users have reported other issues such as freezing mid-game and random erratic behavior. It's hard not to think that these problems are related to the design itself rather than user error. I'll give Moza credit where credit is due – their customer service can be responsive when you need it most. However, the inconsistency in resolving issues is a major concern. You'd think that with a premium price point comes some level of accountability and dedication to quality control.

The Verdict

So who gets my money? If I had to choose between these two, I'd say go for the Moza R21 – but only if you're willing to take on the risk of potential reliability issues. The extra torque and smoother performance might be worth it for some users, but for others, the added stress and anxiety might outweigh any benefits. If you're a casual Sim Racer or just starting out, I'd recommend exploring other options before investing in either the Moza R12 or R21. There are plenty of other wheels on the market that offer better value for money without the baggage of reliability issues.
