bright, beautiful light, but weakness in the base

These bulbs are now the 3rd led, I have installed. The previous flickered, were dark, yellow etc.
These are though only 3.8W, much brighter than many G9 LED with alleged 7w.
Positives:
- Bright
- Nice, slightly whiter light than a normal halogen
- No strobe effect, no flickering, no humming

Neutral:
- The size is really "great", because you in my lamp does not see the bulbs, no negative point. But with a conventional G9 which has nothing to do

Negatives:
- One was broken during shipment
- Very high price
- The biggest negative point is that the only bulb is loose in the socket of the lamp. At first I thought she was not really there, but was to stop it. Other G9 bulbs not stuck in it, this. Therefore, the bulb toward the ground depends also easy.

Due to the beautiful, bright light without flicker, but I keep the lamps.

Meanwhile catch the bulbs to flicker - stuck with it ever 4 at a lamp, then goes to the row ... therefore only 2 stars
