The Lupe Technology is outstanding and it is easy to set up and use. Even the box that the parts arrive in is impressive and the user guide is very clear. Assembly is quick and everything clicks into position first time. The high quality battery is easy to charge and gives over 60 minutes use. The design makes it very versatile and the low weight allows easy access to difficult places around the home or work place. Emptying the bin and cleaning the filters is also straightforward. It's a joy to use and I expect years of many years of trouble free use. I unreservedly recommend it to you. Stephen Tiffany Stockport.
