The parts seem to be ok, hard to say as I haven't had to use them yet but they'll be fine I've no doubt.
Bit surprised at the size of the package (Tiny) but this is because the product photo has all the parts laid out neatly, for some reason I had it in my head they'd be laid out similar in a blister pack or similar, instead of lumped together in a tiny bag, but that said they look well up to the mark.
Syma helis are very durable and can take crashes in their stride, but occasionally parts can break when you are first learning to fly. This set has all the replacement parts you will ever need. Delivery took 13 days from ordering, but no problem they were worth waiting for.
My Great nephew loves the helicopters and I am just thankful for these replacement blades. knowing him he will be crashing them about like crazy until he gets used to them, not that my niece approves of the purchase, apparently he has almost decapitated her on more than one occasion.
Everything you need to keep the S109G Apache going is here. All parts look genuine Syma and are identical to the original items on the heli. A must have spares pack for all S109G owners.Good value for the money.
