Ok after using the Tucker more here is my Overview:
1. It weighs less than a Vikan, just over 100g lighter
2. It has superior cleaning ability on both frames and glass. And I believe that for every scrub done with the Tucker, two are needed with a Vikan to give an equal clean.
3. It retains less water within its bristles, keeping itself light and not clogging with dirt and dirty water
4. for higher work its great, because it more readily splays, it means if you are cleaning at different angles regularly and dont have a swivel this brush is great!!
5. It has more glass coverage than any other brush I have used of a similar size:
stock width of Vikan: 27cm
stock width of Tucker: 27.4cm
fully splayed width of Vikan: 32cm
fully splayed width of Tucker: 36.5cm
stock height of Vikan: 6.7cm
stock height of Tucker: 5.8cm
fully splayed height of Vikan: 14cm
fully splayed height of Tucker: 16.5cm
bristle depth of Vikan: 5.2cm
brislte depth of Tucker 6.2cm
Note: the Vikan had to be held very hard against a flat surface to gain its maximum splay measurments, in reality it would have alot less. While the Tucker didnt need so much pressure.
So basically, it weighs less than a Vikan, covers more glass and does a better job IMO
I compared it against a Vikan because this is what the majority use and know. Its also far better than the Ionic Multipole brush, Bentley, Flocked Oval Vikan, Flocked Rectangular and of course the Mono Rectangular Vikan. Im yet to compare it to the Addis and I may be purchasing a Carbontec brush ( the one that looks identical to the Tucker by Unger )
Hope this helps, Luke
