Mixed Reviews on Durability

Many people who bought this sprinkler commented that it was still going strong for several seasons.  But others commented that it appeared very cheap and made mostly of plastic.

Price and Quality

You are going to pay a lot more for this sprinkler than similar sprinklers.  The question that have people talking, is - why are they paying so much for a mostly plastic sprinkler?  Here is one of the many comments on the high price compared to the quality, "This is not worth the price.  I will go with something else especially if I continue to get no response from customer service. Unfortunately I'm disappointed and could've purchased 3 sprinklers for the price of this one.."

Adjustable

The Gardena 1975 Aquazoom Oscillating Sprinkler can be adjusted to go forward, back, left, and right. There are four levers that control these adjustments.  However, you might get wet trying to get this sprinkler adjusted right.  Because it is fast and can go from one extent to another in 15 seconds or so, customers found that it was hard to make adjustments without getting wet.

The Gardena 1975 Aquazoom Oscillating Sprinkler is an oscillating sprinkler on the upper end of the price spectrum.  It is mostly made of plastic with mixed reviews on durability.  This sprinkler performs well on rectangular lawns.  A nice feature is that it is easy to adjust to reach the areas that you want to water.  There was a lot of discussion and disagreement among customers about the high price versus the quality that you get with this sprinkler.  If you do buy this sprinkler, you will get a 12 month warranty on parts and labor.
