Bests & Worsts Reviews from Amazon

I have read all 400+ reviews, especially the 1,2 star reviews in which the canopy collapsed, usually in light wind. I have now bought 3 of these (note: amazon uses many vendors for these, and price can be anywhere from $73 to $115, if over $90, I'd wait a week and see if price drops), and are obviously made as cheaply as possible. Taking all the suggestions and viewing the failure photos (looks like main problem the failures had was inadequate bracing of the top of the support legs), I have done the following (in hopes of avoiding early failure): 1. Drilled and sheet metal screwed (#8x3/8") the top of the legs to the canopy top frame (very puzzling why these don't have clips like other connections do). Without these screws, the top frame is not attached to the support posts in any way. 2. Securely attached bottom of poles to ground (I didn't use the plastic pieces that came with the set, I used 4' light metal fence posts like Origin Point 090044 Light Duty Fence Post, 4-Feet, pounded into the ground, cut off tops, then drilled hole through top of the cut-off fence post and attached with bolt that came with the set). 3, Bought 4 pieces of 10 foot 1-1/4" PVC pipe ($5.77 each at big box orange hardware store), cut in half, and slid the thin metal support legs inside. Very snug fit, but looks nice, adds strength, and protects car door finish if door is opened against post). 4. Slid 2' pieces of PVC at the joints on the lower horizontal supports where they connect. After assembly, it looked to me that the support was bending at that joint, and likely a weak point. 5. Wrapped exposed joints and welds that come in contact with the tarp with Gorilla duct tape to reduce abrasion of the light tarp. 6. Securely braced the top of the corner posts by screwing pieces of 2x2" wood from the top corners to a nearby fence, so that pushing on the top frame corners results in very little movement. With the stuff done above, in a 20mph wind, the tarp flaps a little, but the frame is solid and doesn't move at all. Cost of additions: $12 fence posts, $22 PVC pipe, $2 duct tape, $1 screws. Time: First basic setup about 1h, 2nd about 30min (2 people). Enhancements, several hours of thinking, 2 hours work for first canopy. 45 min for 2nd. 5/26/17 it is now nearly two years since I wrote the above. The canopies have held up well, no problems. There have been a few storms in which branches fell from the trees which are around the canopies. This has resulted in several small tears in the fabric, I have fixed these with transparent Gorilla tape. It seems to be holding, now a year after applying the tape. I am very satisfied with the product, with the proviso that the additions I listed above are made.
