Quality truck
I think for the price point, this is the best value for the money. This truck is well built and pretty fast. It doesn't do the best on crawler terrain or taller grass. This is ok though, it wasn't meant to be a crawler. I have had it for several months and am not nice to it, hasn't broke yet. I also like the clip less body mounts. Definitely don't regret this purchase. The picture I posted is with bigger tires than it came with.

Very Powerful and Fun to Drive
Very powerful and fun to drive. It feels like a real monster truck in a smaller scale. The performance is great and I’m very satisfied overall. The only downside is that it does not include a charger. Other than that, I’m happy with it.

Fun RC Car!
I got this on sale for $108. This has been one of my better buys. I like this rc car. I got the V2. Downside being the plastic on one of the front outside axels failed and the axel popped out and disappeared somwhere. Waiting on the replacement metal parts now from Arrma ARA-311198($40 bucks). Upgrades add up quick!

Just as fun as the big boys
*1st Thing, this must be a version 2, because there are tons of videos talking about it coming stock with plastic dogbones, differentials and all that. Not anymore, everything including the planetary gears in the diffs are metal (planetary gears look to be aluminum though). And also your Arrma logo on the front won't be white, I did that. Anyway, if you know about Arrma, it's Arrma tough, enough said. If you're new to the hobby, get it, you'll love it. It's tough as a tank, quick for it's size, runs smooth and quiet. If you charge the battery with the accompanied charger, get a higher wattage USB-C cord and use a high wattage charge block and you can charge the battery pretty quickly (less than an hour), otherwise plugging it in your laptop or something like that will take forever.

It's good in stock form
It's fun in stock form, perfect for beginners. But if you go brushless, there's a ton of torque-steer. A gyro is a must. Unless you like to do heavy modifications, leave it in stock form or spend the outrageous price for the spektrum blx esc that comes in the Typhon or Mojave blx versions. I actually regret this buying one. But again, it's perfect for a beginner, just not so much if you buy it planning on going brushless without buying the crazily priced blx system.

Fun car for my 13 y/o! Great Christmas gift.
Got this for my 13 y/o son for Christmas and he loves it. It’s a great RC car for a kid who is transitioning from little kid toys to more adult stuff. At the price point this was the perfect transition car for him. Easy to drive, super fast, durable, decent battery life. The one thing I’ll say is it takes some practice and fiddling to get the body on and off. I don’t love the design. It’s supposed to be super easy and idiotic proof but both my son and I (and my husband) struggle with it.

Great starter RC car. 5yr old loves it
It’s a good starter RC car. Purchased for my 5yr old daughter as she always watches me play with mine and showed interest. Started her on 50% power then moved her up gradually to 100%.

I love Arrma R.C gotta say one of the best makers in a long time, strong and easy to work on and this little grom granite is a blast, its a little slow with the brushed motor but rc 4 wheel drive makes a crazy brushless conversion that makes this granite almost to fast, big fan of these groms

Wird regelmäßig schonungslos von meinem 5 Jährigen Sohn misshandelt 😅 Wasser, riesige Sprünge alles kein Problem. Das Ding hält! Super dass man die Geschwindigkeit drosseln kann, so kann der Zwerg sich in Ruhe damit vertraut machen
