Siphon very good - reasonable price

I bought this for siphon installation of windows, without this assembly would have been impossible,
eg window without opening function with safety glazing, B 1.86 mx H 1.10 m, weight 80 kg.
The investment has paid off, because the siphon sit absolutely fixed, however, requires the prior cleaning of the glass surface, the easiest with a damp microfibre cloth.
With decreasing suction (indicated by a red ring) is simply the pump button repeatedly until you see the red ring is no longer visible - discontinuation of being lifted part or even releasing the suction lifter (as in those with lever) is not necessary.
The siphon at every level and smooth surfaces such as glass, metal, plastic or laminated chipboard,
on normal wood and chipboard and rough surfaces it does not hold.
For example, curved glass surfaces of Woods there is also siphon having a slightly different construction,
these here are not suitable.

Conclusion:
- The investment is absolutely worth it and I can only recommend this siphon.
