Tesla superfans are complaining about its $150 CyberBeer — calling it 'hot garbage' and posting pictures of rusty bottle caps

• Tesla launched a limited edition set of two bottles of CyberBeer and two steins for $150 in October.
• Some Tesla superfans who bought it are saying the bottles are rusty and it tastes like "hot garbage."
• The unboxing experience was "premium," but the beer was "subpar," one customer told Insider. 

Some Tesla superfans aren't thrilled with Tesla's new CyberBeer — and they're taking to social media to air their grievances.
