Bad quality

Having back pain and neck pain I searched Google for rated massagers. Wahl came up as being good. Purchased first one from Dischem, variable speed didn't work. Purchased rechargeable unit and that sounds like the motor dislodged. The first unit was replaced and now the second units attachments are splitting so they don't fit, after being used once? So 3 units in 5 weeks. They have been used at most 30 minutes. Quality is appalling. I am taking the units back today as I purchased a Bennet Read and Carmen massager. Wahl, the units are 3 for 3 on failure after minimum use. Whilst they may be budget and mid range priced units surely they are built to last longer than one or two uses? The rechargeable massager was charged once and must go back. What I find crazy is the Carmen massager is cheaper, works properly, makes no noises and the attachments fit..... unlike Wahl. The Wahl massagers make noise, on two units the variable speed does not work and the attachments are made from rubber which splits. Today the units purchased 2 weeks ago go back. They have been used once each and have both failed...... They will be swapped for Bennet Read.
