Choate +5 Rem 870 Mag Tube extension any good? Junk?

[Ironheart]

Ive been on the fence about ordering one of these +5 mag tube extensions for a while now

I am curious if there are any issues with a mag tube of such great capacity, it will bring my shotgun to a capacity of 10 rounds in the tube

Any shells ever hang up?

Will the spring actually be stong enough?

Any info would be great

Thanks in advance
