One and only complaint, you will need to remove any covers/sleeves from you remote so that it can slip into the docking recess to charge.
Sometimes you need to wiggle the remote to ensure that they dock correctly and the charging light activates as it is possible to drop them in on the wrist straps making the remote sit proud and not charge
I've never had a remote refuse to charge in 2 years.
Have had mine since the wii was released 1st week. So 2 years then.
Never had a problem with it charging and still charging.
I sometimes do not use my wii for weeks due to work shift patterns and the remotes are always charged well and ready to go.
Excellent product holds charge long enough for when i do play to tire me out. I have bought these for friends and family with no bad experiences.
Would buy again.
