Before spending out over £600 on the Facelift, consider Gardiners Ultra-lightweight Superlite pole, it's modular as against telescopic but it is incredibly light and rigid, currently I believe it's the lightest pole on the market...and doesn't cost as much as the Facelift either!
No moving parts so no clamps to wear our or slip..a very impressive pole, as this has the pole hose outside the pole, you only use the sections you need to use...
