First impression great!

Requirements were on my part:
- All! Are dishwasher-resistant.
- Light / single-handed use.
- Neat closure.
- If possible, no suction, as they are rarely completely dishwasher safe, btw. keep on plain difficult to completely germ-free are and I just do not really like.
- Min 0.5l.

For testing, I have ordered two bottles that came packed very quickly and neatly.

The material of the bottle and lid system seems sturdy and well made.

The bottle itself has incl. Cover a total height of about 24cm + ca 7cm diameter. It is provided with an embossed measuring bar in ml, which is slightly crimped at the same time a little better grip on the bottle. On the opposite side is the top of the bottle, a small indentation for the thumb. The bottle is thus well in hand.
Unfortunately, the material of the bottle itself is very smooth, so that when sweaty hands but could be a risk that the bottle could slip out of your hands, if they are not holding properly fixed. I feel this has not yet happened but after several operations.

The closure is a good screw cap which despite the lack of rubber seal tightly closes the transition to the bottle and move up without any problems and can turn.
The drinking nipples on the lid itself has about 2.5 cm in diameter and is about 1.2-2 cm upward / is bevelled) before and so allows a pleasant and decent drinks without Necessary sucking.

The clasp of the drinking spout is twofold: On the one provided with a round plastic handle cover which is internally provided with a nozzle for drinking matching graft and is fastened by snapping. The plastic sheet is also large enough to hook one or two fingers without any problems and "fishing" the bottle in this way. In the open state can be good a Finger in the sheet, so as to keep the lid on the bottle, so that it does not fall on one's nose while drinking.
The second closure is a metal bracket which can be put around the first closure.

The handling is simple and straightforward in the sum.

Meanwhile, the bottles have the early rounds survived in the dishwasher as well as the first full bottle now the first fall from about waist height without damage (small scratches on the outside of the bottle falls here not significant) has survived the opening mechanism.

Although a short test with a carbonated beverage & brief agitation was tight, but the bottle was - as can happen with any other bottle also - under considerable pressure. But as I always prefer non-carbonated drinks, I can respect to long-term comparisons. Dichigkeit say anything further.

So far I had no concept of this manufacturer, but I have to say that I am the first impression of the previously ordered two bottles has convinced the extent that I have ordered more.
