Super fun platform and overall durable with big exception, the differentials. The marketing and box tout metal gears but the differential still has plastic gears inside. The upgraded diffs are super durable but cost about another $50. Making the price point of this rig not as attractive once you buy it. Also Spektrum just needs to stop it with the smart battery crap. Especially IC2. Should come with the metal gears or at least sell a gear set separately.
Fantastic starter rc for my 8 year old. Day three and he can’t stop charging it and going back out. Best Xmas present ever- his words.
Great little truck. Easy to take anywhere. And as always fast shipping from Amain!!
Was supposed to show up today and never did so that's disappointing but I'm sure once I get it I'll enjoy it I love the little groms!
Four verified-owner reviews of the Arrma Granite Grom MEGA 4WD 380 Brushed 1/18 RTR (Green) give mixed feedback. A 3/5 reviewer praises the platform's durability but says the differentials contain plastic gears despite marketing that mentions metal gears, and that upgraded metal diffs cost about $50 more. A 5/5 reviewer, a parent of an 8-year-old, reports the truck held the child's interest, and another 5/5 reviewer calls it a good, easy-to-transport truck with fast shipping. A 1/5 reviewer reports the order never arrived on the expected date, though they expect to enjoy it once received. The reviews are few and the ratings diverge, and the 1/5 review concerns delivery rather than the product itself.
- + Durable platform overall

- + Easy to transport
