Bests & Worsts Reviews from Amazon

First my credentials to write this review. I'm a 30 year old biomedical engineer with about 8 years of design experience for plastic injected molded parts, adhesives for plastics creating chemical bonds, designing of tubing and cabling, waterproofing electronic parts and creating water tight seals. The good: This was a fantastic idea and worked amazingly well for about 4 uses. The bad: The adhesive seal near the fill port failed to the point there the product failed to work anymore. There are some important design flaws that need to be addressed in the next design iteration or gen 2 or 3 of this product. 1) The adhesive seal that I'm talking about perhaps needs more overlap on seal surface, use of different materials or adhesive to properly chemically bond the two plastics. The use of a mechanical seal would be ideal for this as this product has constant pressure and temperature changes against the seal. 2) There needs to be some sort of strain relief on the water tubing as it comes out of the water container. This tubing kinks as you move the shower head around. 3) A shoulder strap for transport the 50lbs of water that you'll be filling this up with. 4) The base of the unit needs to be reinforced somebody to hold up 50lbs of weight on a consistent basis. 5) Some sort of plastic handle should be placed in the center of the handle strap for easier weight distribution in the handle. Again, this is a great product idea, but lacks in proper design principles that make this generation of the product great for a few uses, but will not last. Even if this lasts for a few months or a year, these bonds will eventually fail rendering the product unusable.
