are these studded boots any good?

I have a pair that I used for 3 years the boot is still in good shape,but the studs are worn,however the studs on any boot are going to last the same from boot to boot.I thought they where comfable not as light as the guide boot I have now,but durable(sp)?the one thing is the little metal drain holes on the side of the boot fall off rather fast sent them back they got repaired but the new ones did the samething even sooner.LL bean might have the best deal on wading boots from what alot of the guys here say.I have always used simms.
