We bought the Doro WT87 because of the advertsed longer range. Our existing walkie talkies (Oregon Scientific TP-329) do not work well with the hilly and wooded terrain around our house.
The Doro does have a much better range and is usable for what we need, i.e. to give to the kids so they can explore the countryside but still be in touch. Don't expect miracles, but performance was noticeably better. Other than that they have all the usual features and are small and lightweight.
A nice feature is the ability to lock all the menu controls, to make sure kids fingers/curiosity do not change channel part waythrough their adventure.
The 5th star is reserved for any walkie talkie that has an ever better range.

Good points All

Bad points Can't find any

Other thoughts

It's fantastic

I can truly say I can't find anything to complain about, we have 6 acres of land as we bread Dartmoor ponies, I walked to the furthest point and Julie walked in the opposite direction she rang me I answered the sound was as clear as if she was standing next to me no interference at all.
Now Julie can't ignore me when the phone rings and it's for her and she's down the field "Yes"
Also handy when Julie is riding just in case there's a problem
Thank You
