After some struggles people have had with dolls breaking, we have started making all the "femurs" from metal conduit for all Sinthetics. The dolls that are in production waiting for silicone to be poured have all been retrofitted with the new thighs. Any future dolls will have these new thighs. The weight difference is nominal enough to be insignificant. Matt has done all kinds of stress tests to determine that if someone is able to break these new parts they must be Hercules. It is not possible to retrofit existing dolls to have entirely metal femurs without causing a massive scar and doing huge repairs.
Please continue to pay attention to the correct ways to move the joints and continue trying to learn proper ways if you are uncertain.
Tip of the day: NEVER reposition the legs without bending the knees first. Think about how it would feel for someone to move you that way and be conscious of leverage and angles.
As with everything, if it doesn't want to go the way you are pushing it, stop pushing that way. Also keep in mind that if you did not purchase your dolls new, from us, your warranty is void. One never knows what people do behind closed doors even if they swear they were careful. Even that guy with the saws-all said he was careful...
To the person who was worried about Sinthetics neck breaks - there hasn't been one of those reported in years. Since somewhere in 2012 all Sinthetics have metal-reinforced cross bars in the neck/back. If a doll is properly used, stored, lifted and supported neck issues should not happen.
We hope these upgrades make everyone happy.
