Good value overall

I needed a Cat Shield for my Toyota Prius and found Millercat. The price for the aluminum shield was competitive, and I managed to snag a small discount they had running, which was a nice bonus. Shipping took about 6 days to get to me in Arizona. It felt like a solid purchase for the security it adds.

Reliable protection, as always

This was my third purchase from Millercat, this time for a Lexus RX Cat Shield. I've bought shields for my Honda CR-V and a Toyota Tundra previously, and the quality has always been consistent. The packaging was good, everything arrived without damage, and all the tamper-proof hardware was included. It's reassuring to know exactly what to expect from their products. Shipping was pretty quick this time, reached me in California in 4 days. They just do what they say they'll do, which is why I keep coming back.

So happy with my shield!

Seriously impressed with my new Toyota Tacoma Cat Shield! Installation was straightforward, and it feels incredibly sturdy. My mechanic even commented on the quality. I'm so relieved knowing my catalytic converter is protected now. I will absolutely shop here again for future vehicles and tell my friends with Tacomas and Priuses where to get theirs!

Does the Miller CAT shield actually prevent theft?

G GayatriN 3 weeks ago ✓ Best Answer
It's a deterrent. Makes it harder, takes longer. Most thieves move on.

Is the aluminum cat shield strong enough for a Tundra?

D DeepakM 1 month ago ✓ Best Answer
I went stainless for my F-150. Felt safer.

Stainless is heavier though.

True, but more peace of mind.

Aluminum is fine. It's about deterrent, not bulletproofing.
