This is the absolute best (Southern spring) summer toy ever. We read many of the negative reviews but having worked with pvc pipe before (our daughters bed is made out of pvc pipe) we knew that 1) Pvc pipe is EXPENSIVE! The pipe itself isn't too bad but the connector pieces are quite expensive and add up fast. The cost of the pipe and connectors goes up the thicker the pipe. This toy uses pipe that is quite large so the price would be much more than that of the pipe we used to make her bed. Plus it's colored which is difficult to find and adds an extra cost. So the cost of the pipe alone is worth the $85 of the product. 2) The nature of PVC pipe is that it comes apart easily. You absolutely need to use a rubber mallet to put pvc pipe together. Yes the water buckets fall out if you don't mallet them together. A good few whacks with the mallet and your water and sand buckets should stay put. I've watched my kids playing in this every day since the first end of March (We live in the south, it's the end of May here now and entering the 90's already) and as they continue to touch the pipes and ride their bikes through the 'car wash', even with the mallet the pipes will come apart and need to be whacked back together. The product is not broken, it is still usable. Just push the pipes back together with a good few strong whacks with a rubber mallet. The only negative factor I'd say is the quality of the plastic of the bucket that flips the water. After two months in the sun the bucket is getting weakened by the sun rays and is cracking. I'm sure my husband can drill holes in a sand bucket to replace this but the company should have used a higher quality plastic here. Regardless, for the amount of enjoyment this toy brings my girls and all the neighborhood kids, I still give it five stars. Just be sure to use a rubber mallet when you put it together and keep it handy throughout the summer.
